A New Family Of Cavernicolous Millipedes With The Description Of A New Genus And Species From Idaho (Diplopoda: Chordeumida: Chordeumidea), John S. Buckett, Michael R. Gardner
A New Family Of Cavernicolous Millipedes With The Description Of A New Genus And Species From Idaho (Diplopoda: Chordeumida: Chordeumidea), John S. Buckett, Michael R. Gardner
The Great Lakes Entomologist
The Chordeumidea is accumulating species names faster than any other group of North American Diplopoda. About one-half its species, 47, have been described since 1950. This recent growth has occurred because the small size, localized populations, and, frequently, cave habitus of these millipeds have obstructed thorough collection in the past. These factors have only recently been overcome by comprehensive collecting. As a result of this rapidgrowth and the many artificial groupings which result from it, much organization of the higher classification remains to be done. Hoffman (1961) emphasizes that co- operation between workers, more thorough descriptions, more accurate illustrations, and …
A Melanic Pieris Rapae From Michigan (Lepidoptera: Pierdae), Julian P. Donahue, M. C. Nielsen
A Melanic Pieris Rapae From Michigan (Lepidoptera: Pierdae), Julian P. Donahue, M. C. Nielsen
The Great Lakes Entomologist
The Arthur J. Yates collection of Michigan Lepidoptera, recently donated to Michigan State University (see Fischer, 1967), contained a striking melanic male cabbage butterfly [Pieris rapae (Linnaeus)] (Figs. 1, 2) now incorporated into the MSU series. Yates collected the specimen on 29 May 1934 in Roseville, Macomb County, near the western shore of Lake St. Clair in southeastern Michigan. An examination of the androconia and genitalia, using the characters described by Chang (1963), assured proper identification of the specimen. Although we have found no record of a similar rapae taken in North America, there are some named European forms of …
Botanical Latin: History, Grammar, Syntax, Terminology And Vocabulary. William T. Stearn. London And Edinburgh: Thomas Nelson And Sons, Ltd., 1966. Xiv, 566pp.($14.75), R S. Wilkinson
The Great Lakes Entomologist
Excerpt: As W. T. Stearn reminds us in the preface to this attractive and welcome work, "the realm of literature which a knowledge of botanical Latin opens to botanists is a strange barbarous place for classicists; invited into it as an interpreter, a good classical scholar may well feel like Alice meeting Humpty Dumpty through the looking-glass." The same perplexity is experienced by the entomologist; those of us educated in the Latin of Cicero and Pliny are ill equipped to name new species or even to translate Latin descriptions, as biological Latin developed long ago into a stylized form not …
Insect Behaviour. Symposium No. 3 Of The Royal Entomological Society Of London. Ed. P. T. Haskell. London: The Royal Entomological Society, 1966. Viii, 113 Pp. $6.35. .., Anthony Eve
The Great Lakes Entomologist
Excerpt: The science of zoology is expanding at such a rate that it is difficult for even the relatively narrow specialist to keep up with the ever- increasing literature on his subject, and almost impossible to assimilate recent findings in the entire field of zoological research. The international congresses of zoology and entomology have helped, considerably by facilitating personal contact between workers of different nationalities. On a more modest scale, the symposia of the Royal Entomological Society of London have provided a useful means of bringing together entomologists in an atmosphere conducive to the free exchange of ideas and information.
Laminating Lepidoptera For Educational Use, Darryl Quidort
Laminating Lepidoptera For Educational Use, Darryl Quidort
The Great Lakes Entomologist
Excerpt: A convenient method of teaching farmers, 4-H members and students to recognize various species of Lepidoptera is now being used in Michigan with wide success. In the process, insect wings are mounted on cardboard and sealed between layers of clear plastic. The resulting "laminations" have several advantages over pin-mounted Lepidoptera, and are admirably suited for any use that requires constant handling. The finished mounts are impervious to museum pests, are dust-proof, may be cleaned with ease, and are easily stored in a loose-leaf binder. The plastic is flexible, thus danger of damage from bending is slight.
The Behavior Of Atlanticus Testaceus (Orthoptera: Tettigoniidae) On The E.S. George Reserve, Michigan, S. K. Gangwere
The Behavior Of Atlanticus Testaceus (Orthoptera: Tettigoniidae) On The E.S. George Reserve, Michigan, S. K. Gangwere
The Great Lakes Entomologist
Several reports deal in part with the systematics, distribution, or habits of one or another of the shield-backed katydids of the orthopteran genus Atlanticus. Included are Blatchley (1920), Cantrall (1943), Caudell (1907), Davis (1893), Hebard (1934), McNeill (1891), Rehn and Hebard (1916), and Scudder (1894). One species of the genus, A. testaceus (Scudder), is found commonly throughout Michigan and has interesting habits. As the species' feeding behavior was poorly understood, the author undertook an investigation dealing with that subject. The results are in press. During the course of that study much information was obtained on certain non-feeding aspects of the …
A New Species Of Thraulodes From New Mexico (Ephemeroptera: Leptophlebiidae), Richard W. Koss
A New Species Of Thraulodes From New Mexico (Ephemeroptera: Leptophlebiidae), Richard W. Koss
The Great Lakes Entomologist
While working on the Ephemeroptera collection in the Entomology Museum at Michigan State University, the author came upon a single specimen of Thraulodes which appeared to be a new species. Although it is only in fair condition (the preserving fluid having dissipated under field conditions), the colors are well preserved and very distinctive. The specimen was sent to Dr. Jay R. Traver, University of Massachusetts, who confirmed suspicions that the specimen was new. I have been informed by Dr. Traver that she and Dr. George F. Edmunds Jr. are presently engaged in a revisionary study of the genus for North …
Another Record Of Williamsonia Fletcheri In Michigan (Odonata: Corduliidae), David F. Foley
Another Record Of Williamsonia Fletcheri In Michigan (Odonata: Corduliidae), David F. Foley
The Great Lakes Entomologist
Excerpt: Williamsonia fletcheri Williamson was first taken in the United States in the upper peninsula of Michigan near Manistique, Schoolcraft County (Gloyd, 1932). On June 4, 1966, I collected two males of this rare species at Island Lake, a small lake heavily overgrown with jack pine and poplar in southeastern Grand Traverse County. The specimens were identified by Mrs. Leonora Gloyd of the University of Michigan. This is the first report of this species from the lower peninsula of Michigan, and the second for the United States.
Some Notes On Heteropteran Trichobothria, Carl W. Schaefer
Some Notes On Heteropteran Trichobothria, Carl W. Schaefer
The Great Lakes Entomologist
Excerpt: There has been much recent interest in the comparative morphology of the Heteroptera. This work has emphasized the land bugs, or Geocorisae, and has been concerned with working out the relationships and taxonomic placement of the higher categories (categories above the genus), and with the phylogenetic lines and sequences of these higher categories. The geocorisine groups with which I have been most concerned are in the closely related superfamilies Lygaeoidea, Pyrrho- coroidea, and Coreoidea (see Schaefer, 1964, for a discussion of the relationships among these groups). Another superfamily, the Pentatomoidea, is less closely related. All four of these superfamilies …
A Review Of The North American Species Of The Genus Otites Latreille, With Descriptions Of Two New Species (Diptera: Otitidae), George C. Steyskal
A Review Of The North American Species Of The Genus Otites Latreille, With Descriptions Of Two New Species (Diptera: Otitidae), George C. Steyskal
The Great Lakes Entomologist
Excerpt: In 1961 (Steyskal, 1961), I placed the genus Otites in a key to the North American genera of Otitidae and indicated the synonymy of the genus Ortalimyia. Bibliography and synonymy of the hitherto known species of our area will be found in the Catalog of the Diptera of America North of Mexico (Stone et al., 1965). The only previously published key to our species was by Hendel (1911, as Ortalis), wherein were included Cevoxys latiusculus (Loew) and the four species now known as Otites bimaculahs (Hendel), 0. evythvocephala (Hendel), 0. pyvvhocephala (Loew), and O. stigma (Hendel). The present treat- …
The Genus Phragmatobia In North America, With The Description Of A New Species (Lepidoptera: Arctiidae), Julian P. Donahue, John H. Newman
The Genus Phragmatobia In North America, With The Description Of A New Species (Lepidoptera: Arctiidae), Julian P. Donahue, John H. Newman
The Great Lakes Entomologist
Excerpt: This paper, based on the examination of 1,879 specimens, serves to resolve the taxonomic problems involving the three North American species of Phragmatobia. The genus Phragmatobia, the ruby tiger moths, has had a checkered history since it was described by Stephens in 1829 (type, by monotypy, Noctua j'uliginosa Linnaeus, 1758). Although many species have been described in or transferred to this genus, in both the Old and New Worlds, most of them have been removed to other genera. By 1902 Dyar recognized only two North American species, a status since then unchanged (McDunnough, 1938; Forbes, 1960). Despite the recent …
Ixodes Brunneus (Acari: Ixodidae) From Two Bird Hosts: A New Michigan Tick, Richard S. Keith, Brenda S. Keith, William C. Scharf, Sarah A. Hamer
Ixodes Brunneus (Acari: Ixodidae) From Two Bird Hosts: A New Michigan Tick, Richard S. Keith, Brenda S. Keith, William C. Scharf, Sarah A. Hamer
The Great Lakes Entomologist
The tick Ixodes brunneus Koch (Acari: Ixodidae) is reported for the first time in Michigan from two bird hosts at two locations in the lower peninsula. All stages of this tick exclusively feed on birds, and are primarily known from the southern U.S., although abundant records occur from northern states. The role of this species as a vector of pathogens is discussed.
First Report Of Leptomantispa Pulchella (Banks, 1912) (Neuroptera: Mantispidae) From Iowa, Edwin L. Freese, Paul K. Lago
First Report Of Leptomantispa Pulchella (Banks, 1912) (Neuroptera: Mantispidae) From Iowa, Edwin L. Freese, Paul K. Lago
The Great Lakes Entomologist
An adult specimen of Leptomantispa pulchella (Banks) (Neuroptera: Mantispidae) was collected in southeast Iowa. Published records indicate the species is present in southwestern Canada and much of Central America, but this is the first published report of this species from Iowa.
Feeding Records Of True Bugs (Hemiptera: Heteroptera) From Wisconsin, Supplement, Andrew H. Williams
Feeding Records Of True Bugs (Hemiptera: Heteroptera) From Wisconsin, Supplement, Andrew H. Williams
The Great Lakes Entomologist
In order to understand any animal and its habitat requirements, we must know what it eats. Reported here are observations of feeding by 27 species of true bugs (Hemiptera: Heteroptera) encountered in various habitats in Wisconsin over the years 2003–2014. This is the first report of Anasa repetita Heidemann (Coreidae) from Wisconsin.
Macromia Alleghaniensis (Odonata: Macromiidae): New For Michigan, With Clarifications Of Northern Records, Julie A. Craves, Darrin S. O’Brien
Macromia Alleghaniensis (Odonata: Macromiidae): New For Michigan, With Clarifications Of Northern Records, Julie A. Craves, Darrin S. O’Brien
The Great Lakes Entomologist
An Alleghany River Cruiser, Macromia alleghaniensis Williamson (Odonata: Macromiidae), collected in Cass County, Michigan on 18 June 2014, represents the first record of the species for the state, as well as the northernmost unequivocal record in North America. Other records north of 40° latitude are clarified and discussed.
Occurrence Of Treehopper (Hemiptera: Membracidae) Bycatch On Purple Panel Traps And Lindgren Funnel Traps In Pennsylvania, With New State Records, Lawrence Barringer
Occurrence Of Treehopper (Hemiptera: Membracidae) Bycatch On Purple Panel Traps And Lindgren Funnel Traps In Pennsylvania, With New State Records, Lawrence Barringer
The Great Lakes Entomologist
Surveys for invasive insects in Pennsylvania conducted from 2009-2013 captured large numbers of native treehoppers (Hemiptera: Membracidae). These were collected using Lindgren funnel traps and purple prism traps totaling 1,434 specimens in eight tribes, 20 genera, and 57 species. As a result of this work Pennsylvania now has four new published species records: Heliria gibberata Ball 1925, Palonica pyramidata (Uhler 1877), Telamona projecta Butler 1877, and Telamona westcotti Goding 1893. With proper site selection Lindgren funnel traps may be able to capture ten to hundreds of treehoppers in a single season, especially within the Smiliinae: Smiliini and Telamonini.
Infrared Lighting Does Not Suppress Catch Of Codling Moth (Lepidoptera: Tortricidae) In Pheromone-Baited Monitoring Traps, C. G. Adams, P. S. Mcghee, J. R. Miller
Infrared Lighting Does Not Suppress Catch Of Codling Moth (Lepidoptera: Tortricidae) In Pheromone-Baited Monitoring Traps, C. G. Adams, P. S. Mcghee, J. R. Miller
The Great Lakes Entomologist
Video cameras are increasingly being used to record insect behaviors in the field over prolonged intervals. A nagging question about crepuscular and nocturnal recordings is whether or not infrared light emitted by such cameras to illuminate the scene influences the behaviors of the subjects or study outcomes. Here we quantified catches of male codling moths, Cydia pomonella (L.), responding to sex pheromone-baited monitoring traps illuminated with infrared, red, white, or no light. No statistically significant differences were found between any of these treatments.
Gallery Characteristics And Life History Of The Ambrosia Beetle Trypodendron Betulae (Coleoptera: Curculionidae: Scolytinae) In Birch, Richard A. Roeper, Michael Allen, Teresa Hutchinson, Corrina Quidot, Mark Bunce
Gallery Characteristics And Life History Of The Ambrosia Beetle Trypodendron Betulae (Coleoptera: Curculionidae: Scolytinae) In Birch, Richard A. Roeper, Michael Allen, Teresa Hutchinson, Corrina Quidot, Mark Bunce
The Great Lakes Entomologist
Trypodendron betulae Swaine distributed attack entrance holes uniformly over the surface of standing stressed sub-canopy birch trees. Male and female pairs constructed galleries consisting of an entrance tunnel about 20 mm in length and then primary and secondary lateral tunnels averaging between 16 and 23 mm in length into the sapwood. Egg niches were constructed in the lateral tunnels after the symbiotic fungus was established in the galleries. Larvae enlarged the niches into cradles. Pupae and eventually teneral adults developed in the cradles. The sex ratio of resulting progeny adults was approximately one to one, and they emerged from galleries …
Decline In Relative Abundance Of Hippodamia Convergens (Coleoptera: Coccinellidae) In Fall Shoreline Aggregations On Western Lake Superior, Wayne P. Steffens, Ryan P. Lumen
Decline In Relative Abundance Of Hippodamia Convergens (Coleoptera: Coccinellidae) In Fall Shoreline Aggregations On Western Lake Superior, Wayne P. Steffens, Ryan P. Lumen
The Great Lakes Entomologist
In the 1970s, migratory coccinellid aggregations on western Lake Superior shorelines consisted of over 90% Hippodamia convergens Guérin-Méneville. In 2014, the alien Harmonia axyridis (Pallas) accounted for over 80% of shoreline coccinellid aggregations and H. convergens declined to less than 10% of the total. Additional work is needed to elucidate the extent and cause of the decline of H. convergens in western Lake Superior shoreline aggregations.
Occurrence Of A Gynandromorphic Bombus Bimaculatus (Hymenoptera: Apidae) In Southeastern Ohio, Malisa R. Spring, Katy S. Lustofin, Mary M. Gardiner
Occurrence Of A Gynandromorphic Bombus Bimaculatus (Hymenoptera: Apidae) In Southeastern Ohio, Malisa R. Spring, Katy S. Lustofin, Mary M. Gardiner
The Great Lakes Entomologist
Herein, we introduce the first reported case of gynandromorphy in the bumblebee Bombus bimaculatus (Cresson) (Hymenoptera: Apidae), a relatively common North American species found east of the Mississippi River. The specimen was collected in Marietta, Ohio as part of a bee diversity assessment project for Washington County. Gynanders exhibit discrete male and female characters in a single individual. We discuss the potential causes of gynandromorphy exhibited by this specimen, which has differing antennal segments (12 and 13), facial maculation, abdominal hair coloration, and the presence of a corbicula – secondary sex characters that are characteristic for the genus Bombus.
New Records Of Native And Non-Native Bark And Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) In Illinois, Charles Helm, Brenda Molano-Flores
New Records Of Native And Non-Native Bark And Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) In Illinois, Charles Helm, Brenda Molano-Flores
The Great Lakes Entomologist
From 2009–2012, we conducted surveys with Lindgren funnel traps for native and non-native bark and ambrosia beetles (Coleoptera: Curculionidae: Scolytinae) in northeastern Illinois. During this study, we collected a total of 10,194 bark and ambrosia beetles representing 50 species in 28 genera. Ten scolytine species not previously reported to occur in Illinois were collected during this survey. Three of these new records are species not native to North America, including Cyclorhipidion bodoanum (Reitter), Cyclorhipidion pelliculosum (Eichhoff), and Hylastinus obscurus (Marsham). Native species reported from Illinois for the first time include: Anisandrus obesus (LeConte), Dryocoetes autographus (Ratzeburg), Hylocurus spadix Blackman, Pityophthorus …
Comments On A Major Range Extension Of The Little-Known Acrocera Bakeri (Diptera: Acroceridae), Derek A. Woller, Sandor L. Kelly, Daniel K. Young
Comments On A Major Range Extension Of The Little-Known Acrocera Bakeri (Diptera: Acroceridae), Derek A. Woller, Sandor L. Kelly, Daniel K. Young
The Great Lakes Entomologist
The spider fly Acrocera bakeri Coquillett, 1904 (Diptera: Acroceridae) is reported as a new state record for Wisconsin. This is a major range extension, because this rarely-encountered species was previously known only from the western U.S., specifically Arizona, California, and Nevada. The taxonomic history of the species is briefly discussed and hypotheses are offered for its unexpected presence in Wisconsin.
Detection Of Hemlock Woolly Adelgid (Hemiptera: Adelgidae) Infestations With Sticky Traps, Jeffrey G. Fidgen, Mark C. Whitmore, Jean J. Turgeon
Detection Of Hemlock Woolly Adelgid (Hemiptera: Adelgidae) Infestations With Sticky Traps, Jeffrey G. Fidgen, Mark C. Whitmore, Jean J. Turgeon
The Great Lakes Entomologist
We deployed sticky traps underneath the crown of eastern hemlock, Tsuga canadensis (L.) Carrière, to assess their sensitivity at detecting crawlers (1st instar nymphs) of the non-native hemlock woolly adelgid, Adelges tsugae Annand (Hemiptera: Adelgidae). We found these traps more sensitive at detecting infested trees with low densities of A. tsugae than branch-tip sampling with pole pruners. We observed two peaks of crawler abundance at all sites: these peaks likely represented the timing of the progrediens and sistens crawler stages of A. tsugae. Deployment of sticky traps in treated and high-risk stands may prove useful at detecting residual and new …
Ecological Traits Fail To Consistently Predict Moth Species Persistance In Managed Forest Stands, Keith S. Summerville
Ecological Traits Fail To Consistently Predict Moth Species Persistance In Managed Forest Stands, Keith S. Summerville
The Great Lakes Entomologist
Species traits have been used as predictors of species extinction and colonization probabilities in fragmented landscapes. Thus far, trait-based analytical frameworks have been less commonly employed as predictive tools for species persistence following a disturbance. I tested whether life history traits, dietary traits, and functional traits were correlated with moth species persistence probabilities in forest stands subjected to varying levels of timber harvest. Three harvest treatments were used: control stands (unharvested since 1960), shelterwood cut stands (15% canopy removed), and patch cut stands (80% standing bole removed). Logistic regression models were built to assess whether species persistence probabilities were a …
Observations Of Xyleborus Affinis Eichhoff (Coleoptera:Curculionidae:Scolytinae) In Central Michigan, Richard A. Roeper, Mark A. Bunce, John E. Harlan, Richard G. Bowker
Observations Of Xyleborus Affinis Eichhoff (Coleoptera:Curculionidae:Scolytinae) In Central Michigan, Richard A. Roeper, Mark A. Bunce, John E. Harlan, Richard G. Bowker
The Great Lakes Entomologist
Xyleborus affinis Eichhoff colonized wind thrown timber in the moist floodplain habitats of Central Michigan. Single adult females constructed a complex gallery system consisting of phloem–sapwood interface tunnels and sapwood tunnels. An average of 24 progeny adults and a sex ratio of 14 females to 1 male were found in mature galleries after the first of September.
European Springtails Orchesella Cincta (L.) And O. Villosa (L.) (Collembola: Entomobryidae): Vagabond Species Of The Nearctic Region, Catherine L. Smith, John K. Moulton, Ernest C. Bernard
European Springtails Orchesella Cincta (L.) And O. Villosa (L.) (Collembola: Entomobryidae): Vagabond Species Of The Nearctic Region, Catherine L. Smith, John K. Moulton, Ernest C. Bernard
The Great Lakes Entomologist
North American specimens of the European invasive springtail Orchesella cincta (L.) were compared to several published European haplotypes in a phylogenetic framework using likelihood methods based on a portion of cytochrome oxidase II (cox2). Our analyses provide direct evidence of at least two distinct introductions of this invasive to North America from different regions of Europe. Additional introduction events cannot be ruled out because detection is limited by extremely low sequence divergence among populations inhabiting different regions of the continent. Orchesella villosa (L.), another invasive from Europe, is another candidate for multiple introductions. Herein we include the cox2 sequence from …

The David-Gardiner Method Of Feeding Lepidopterous Larvae On A Semi-Synthetic Diet, Ronald Sterne Wilkinson
The David-Gardiner Method Of Feeding Lepidopterous Larvae On A Semi-Synthetic Diet, Ronald Sterne Wilkinson
The Great Lakes Entomologist
[excerpt] One of the most interesting entomological developments in re- cent years has been the introduction of semi-synthetic diets for feed- ing lepidopterous larvae. Vanderzant and Reiser (1956a, 1956b) reared pink bollworms (Pectinophora gossypiella) on such a medium. The medium was subsequently modified by Ignoffo (1963), who experimented with mass-rearing of the cabbage looper (Trichoplusia ni), and by oth- ers. The method showing the most spectacular results is that of David and Gardiner (19651, which, since its publication, has been proven suitable for a number of species with diverse feeding habits. Although not a universal pabulum for larvae, the David-Gardiner …
Relative Susceptibilities Of Three Ponderosa Pine Sources To European Pine Sawfly (Hymenoptera: Diprionidae) Attack In Michigan, Louis F. Wilson
Relative Susceptibilities Of Three Ponderosa Pine Sources To European Pine Sawfly (Hymenoptera: Diprionidae) Attack In Michigan, Louis F. Wilson
The Great Lakes Entomologist
[excerpt] Accidentally introduced into New Jersey about 1925, the European pine sawfly, Neodiprion sertifer (Geoffroy), now inhabits most of the Northeastern and North Central States and Ontario, Canada. Red pine, Pinus resinosa Aiton, and most other native and exotic pines within its range are susceptible to attack. Few attack records are available for ponderosa pine, P. ponderosa Douglas ex Lawson, because this pine is uncommon in eastern North America. Soraci (1939) ob- served egg clusters and larval feeding on planted red and ponderosa pine in New Jersey; Benjamin et al. (1955) found egg clusters on ponderosa pine in Illinois and …
A New Nearctic Triclistus (Hymenoptera: Ichneumonidae), R. W. Carlson
A New Nearctic Triclistus (Hymenoptera: Ichneumonidae), R. W. Carlson
The Great Lakes Entomologist
[excerpt] When Townes and Townes (1959) revised the genus Triclistus along with the rest of the Nearctic Metopiinae, they decided not to describe what was thought likely to be an additional new species, because only one male specimen was known. More recently, additional specimens, both males and females, were collected. From the females, which are even more distinctive than the males, it was easily seen that the species described below is indeed a new one.
