Nocturnal Flight Periodicity Of Caddisflies (Trichoptera) Along The Lake Huron Shoreline Of Drummond Island, Michigan (Usa), Robert A. Haack, David Houghton Sep 2025

Nocturnal Flight Periodicity Of Caddisflies (Trichoptera) Along The Lake Huron Shoreline Of Drummond Island, Michigan (Usa), Robert A. Haack, David Houghton

The Great Lakes Entomologist

Over 7000 caddisfly specimens, representing 33 species in 10 families, were collected between sunset and sunrise on 12 nights: three nights each during early July and early August in both 2023 and 2024. Collections were made on the southwestern side of Drummond Island along the shoreline of Lake Huron. Sampling occurred for five minutes at 15-minute intervals from near sunset (21:00) to 01:00 and then once again at 03:00 and 05:00. Nocturnal flight periodicity was broadly similar between years and months, with mean caddisfly abundance and species richness peaking at about one hour after sunset. Mean species accumulation varied between …


Initial Changes In Ground Beetle (Carabidae: Coleoptera) Assemblages After Creating Gaps Of Varying Sizes In Mature Northern Hardwoods Forests In Wisconsin, Robert A. Haack, Robert E. Acciavatti, Toby R. Petrice, Robert L. Davidson, Terry F. Strong Sep 2025

Initial Changes In Ground Beetle (Carabidae: Coleoptera) Assemblages After Creating Gaps Of Varying Sizes In Mature Northern Hardwoods Forests In Wisconsin, Robert A. Haack, Robert E. Acciavatti, Toby R. Petrice, Robert L. Davidson, Terry F. Strong

The Great Lakes Entomologist

Managers of northern hardwood forests in the Great Lakes region create gaps in the forest canopy of various sizes during harvesting to achieve different silvicultural objectives. Single-tree harvesting favors recruitment of shade-tolerant tree species by creating small gaps in the canopy, whereas group selection creates larger gaps that can favor shade-intolerant tree species. We evaluated changes in carabid beetle abundance and diversity in harvest-created gaps of five sizes (gap diameters of 6, 10, 20, 30, and 46 m) and uncut forests in northern Wisconsin where sugar maple (Acer saccharum) was the dominant tree species. Gaps were cut during …

A Teratomorphic Stonefly (Plecoptera: Nemouridae), Allen W. Knight, Clifford A. Siegfried Aug 2025

A Teratomorphic Stonefly (Plecoptera: Nemouridae), Allen W. Knight, Clifford A. Siegfried

The Great Lakes Entomologist

A single nymph of over 2000 specimens of Taeniopteryx nivalis collected in 1968 from Gull Creek, Kalamazoo County, Michigan (T25:R9W:S6), had a double flagellum on the left antenna (Fig. 1). The more laterally placed flagellum was perfectly formed and of normal length, whereas the inner one was less than half the normal length but appeared normally structured. The flagella shared a common pedicel.


Pollination Of Staghorn Sumac By Ants, Orin G. Gelderloos Aug 2025

Pollination Of Staghorn Sumac By Ants, Orin G. Gelderloos

The Great Lakes Entomologist

[Excerpt]

A population of worker ants, Prenolepis imparis Say (Hymenoptera: Formicidae), was observed pollinating the hermaphroditic flowers of staghorn sumac, Rhus nphina. at the University of Michigan-Dearborn in western Wayne County, Michigan, during the midmorning hours of 10 June, 1974, and at a height of approximately 1.75 m.


Color Variation In Strangalia Bicolor (Coleoptera: Cerambycidae), D. C.L. Gosling Aug 2025

Color Variation In Strangalia Bicolor (Coleoptera: Cerambycidae), D. C.L. Gosling

The Great Lakes Entomologist

[Excerpt]

Many species of Lepturinae are noted for their great variation in color, while some are quite uniform in coloration. Strangalia bicolor (Swederus) is one of the Iatter type and usually shows virtually no variation. The elytra are uniformly blue-black with the exception of the inflexed corner of the humerus which is reddish-yellow. The wings and eyes are black, and the rest of the beetle is entirely reddish-yellow. Until recently, the only variation I had observed was one female with a small, triangular, reddish-yellow spot on the basal margin of each elytron near the scutellum. Linsley and Chemsak (1977) recorded …


Boyeria Grafiana, A Rare Ohio Dragonfly (Odonata: Aeshnidae), T. E. Perry Aug 2025

Boyeria Grafiana, A Rare Ohio Dragonfly (Odonata: Aeshnidae), T. E. Perry

The Great Lakes Entomologist

[excerpt]

The intent of this paper is to record the dragonfly Boyeria grafiana Williamson as a resident Ohio species. The previous Ohio record for grafiana was based on a single male taken by E. E. Bogue at Orwell, Ashtabula County, Ohio, in September, 1894, and listed by Kellicott (1899) as Boyeria vinosa (Say). Hine (1913) updated some of Kellicott's work and identified the Orwell record as Boyeria grafiana, which had been described by Williamson in 1907.


Rev. Modestus Wirtner: Biographical Sketch And Additions And Corrections To The Miridae In His 1904 List Of Western Pennsylvania Hemiptera, A. G. Wheeler Jr., Thomas J. Henry Aug 2025

Rev. Modestus Wirtner: Biographical Sketch And Additions And Corrections To The Miridae In His 1904 List Of Western Pennsylvania Hemiptera, A. G. Wheeler Jr., Thomas J. Henry

The Great Lakes Entomologist

[Excerpt]

The Rev. Modestus Wirtner's (1904) list of western Pennsylvania Hemiptera remains as the only useful general account of this group for the state. Earlier, Rathvon (1869) had published a short list of species from Lancaster County, but because the identity of species referred to cannot be established, his list has limited value.


The Distribution Of Some Soil Arthropods In A Manipulated Ecosystem, James H. Shaddy, James W. Butcher Aug 2025

The Distribution Of Some Soil Arthropods In A Manipulated Ecosystem, James H. Shaddy, James W. Butcher

The Great Lakes Entomologist

[Excerpt] Soil cultivation practices and agricultural utilization affect soil animal populations in various ways. Gisin (1955) and Schalk (1968) concluded that the effect was minimal. Others observed a deleterious effect (Karg, 1956; Sheals, 1956; Strebel, 1957; Aleinikova and Utrobina, 1975; Edwards and Lofty, 1975). However, some soil animals appear to be benefited (Aleinikova and Utrobina, 1975; Edwards and Lofty, 1975). The effects of cultivation and many other factors have been discussed thoroughly in reviews by Christiansen (1964), Burges and Raw (1967), Butcher, et al. (1971), Ghilarov (1975), and Wallwork (1976).


Survey For Parasites Of The Introduced Pine Sawfly, Dlprlon Slmllls (Hymenoptera: Diprionidae), In Minnesota, L. C. Thompson, H. M. Kulman, W. D. Valovage Aug 2025

Survey For Parasites Of The Introduced Pine Sawfly, Dlprlon Slmllls (Hymenoptera: Diprionidae), In Minnesota, L. C. Thompson, H. M. Kulman, W. D. Valovage

The Great Lakes Entomologist

Diprion similis (Hartig) cocoons were collected at 24 sites in 14 counties in north and central Minnesota in 1975 to determine the current status of the parasite complex. The ichneumon Exenterus amictorius (Panzer) was by far the most abundant of the 16 parasites, with parasitization in excess of 44% in both sawfly generations. Parasitization by E. amictorius did not decrease substantially in the second generation, as was anticipated from previous studies. Monodontomerus dentipes (Dalman) (Torymidae) and Delomerista japonica diprionis Cushman (Ichneumonidae) were common only in the second generation. One specimen of Perilampus hyalinus Say (Perilampidae) was reared for the fust …


Distribution Of Acalymma Vittata And Diabrotica Virgifera (Coleoptera: Chrysomelidae) On Cucurbits, Catherine E. Bach Aug 2025

Distribution Of Acalymma Vittata And Diabrotica Virgifera (Coleoptera: Chrysomelidae) On Cucurbits, Catherine E. Bach

The Great Lakes Entomologist

The striped cucumber beetle, Acalymma vittata (Fabricius) and the western corn rootworm, Diahrotica virgifera LeConte, are of economic importance and utilize cucurbits, but to a different extent. A. vittata is a specialist on cucurbits during all stages of its life cycle, whereas D. virgifera feeds on cucurbits only as an adult. Much is known about the life history, feeding preferences, and control of each of these species (A. vittata: Gould, 1944, 1962; Harcourt and Cass, 1955; Wiseman, Hall, and Painter, 1962; D. virgifera: Chiang, 1973; Ludwig, 1975). However, no study has looked at possible interactions such as competition between the …


Invertebrate Predators Of Michigan Lepidoptera, M. C. Nielson Aug 2025

Invertebrate Predators Of Michigan Lepidoptera, M. C. Nielson

The Great Lakes Entomologist

[Excerpt]

For many years this author has been actively collecting Michigan Lepidoptera and generally observing insects in the field. Almost every season some predation of Lepidoptera by insects and their allies is seen. Unfortunately, many early observations went unrecorded in my field notebooks, but since the late 1950's I have made notations of these interesting encounters.


A Distinctive Dune Form Of The Marbled White Butterfly, Euchloe Olympia (Lepidoptera: Pieridae) In The Great Lakes Area, Warren Herb Wagner Jr. Aug 2025

A Distinctive Dune Form Of The Marbled White Butterfly, Euchloe Olympia (Lepidoptera: Pieridae) In The Great Lakes Area, Warren Herb Wagner Jr.

The Great Lakes Entomologist

[Excerpt]

The dunes along the shores of Lake Huron in the vicinity of Ipperwash Provincial Park, Port Franks, and Pinery Provincial Park, Ontario, are notable for their unusual vegetation and a number of interesting plants and animals. During studies of the peculiar, disjunctive populations of the dwarf hackberry tree (Celtis tenuifolia Nutt.) (Wagner, 1974), I became aware that the local population of marbled white, Euchloe olympia (Edwards), differed in a number of respects from the usual form with which I was familiar. Preliminary observations during the spring of 1975 suggested that the butterflies might even represent a distinct subspecies, so …


Development And Survival Of Saratoga Spittlebug Nymphs On Alternate Host Plants, Louis F. Wilson, George C. Heaton, Patrick C. Kennedy Aug 2025

Development And Survival Of Saratoga Spittlebug Nymphs On Alternate Host Plants, Louis F. Wilson, George C. Heaton, Patrick C. Kennedy

The Great Lakes Entomologist

\!hen abundant, the adult Saratoga spittlebug, Aphrophora smatogensis (Fitch), injures or kills young red pine, Pinus rerinovr Ait., and jack pine, P. banksiana Lamb. Its abundance depends greatly on the quantit). and quality of woody plants and forbs of the forest floor that senre a5 alternate hosts during the nymphal stages (Anderson, 1947; Ewan, 1961: Kennedy and Wilson, 1971; Secrest, 1944). Sweet-fern, Comptonia peregrina Coult., is the principal and most important alternate host (Kennedy and Wilson, 1971), but little is know-n about the value of other woody plants and forbs for supporting nymphal development. Therefore, \ve sought to examine the …


Parasites Of Lepidopterous Larvae In Alfalfa And Soybeans In Central Illinois, S. J. Roberts, W. K. Mellors, E. J. Armbrust Aug 2025

Parasites Of Lepidopterous Larvae In Alfalfa And Soybeans In Central Illinois, S. J. Roberts, W. K. Mellors, E. J. Armbrust

The Great Lakes Entomologist

During the 1971-72 soaing season sweep-net samples were taken to determine the major species of parasites and lepidopterous host larvae present in central Illinois soybeans and alfalfa. A trod of 27 primary Hymenoptera and Diptera parasites was collected from nine Lepidopterous species. Parasites were associated with all nine species of Ian-ae m alfalfa and soybeans. Apanteles flaviconchae Riley was responsible for over 87% of &e parasitism of Colias spp. larvae in both alfalfa and soybeans in 1971. The hyperparasites Mesochorus discitergus (Say) and M. arnericanus Cresson were recovered from fou~of dep rim= parasites Pathogens were found in six species of …


A Technique For Estimating The Number Of Shoots On Pole-Sized Red Pine: The Relationship Of Selected Tree Parameters To Number Of Shoots In Central Wisconsin Sand Plains Plantations, J. H. Hainze, D. M. Benjamin Jul 2025

A Technique For Estimating The Number Of Shoots On Pole-Sized Red Pine: The Relationship Of Selected Tree Parameters To Number Of Shoots In Central Wisconsin Sand Plains Plantations, J. H. Hainze, D. M. Benjamin

The Great Lakes Entomologist

Diameter at breast height (dbh) , of ten tree parameters tested, was most highly correlated with the number of shoots per tree in six red pine plantations in the central Wisconsin sand plains. Tree height, frequently used as an estimator of shoot number in young conifers, was not highly correlated with shoot number. A strong, nonlinear correlation existed between branch diameter and number of shoots per branch. Multiple regressions using several tree parameters yielded the highest R2 values, however, dbh was judged the simplest and most practical estimator of shoot number for central Wisconsin red pine plantations.


Effect Of Artificial Defoliation On Broccoli Yield, W. S. Cranshaw, R. J. Default Jul 2025

Effect Of Artificial Defoliation On Broccoli Yield, W. S. Cranshaw, R. J. Default

The Great Lakes Entomologist

Broccoli plants were artificially defoliated at varying plant growth stages and defoliation intensities to determine bases for control decisions with lepidopterous defoliators. Low levels of defoliation (<25%) did not significantly depress head weight at any treatment date. Higher levels of defoliation severity (50%) depressed head weight when inflicted following the development of small (<2 cm) heads. Only complete defoliation (100%) consistently affected head weights. Because of the great ability of broccoli plants to compensate for leaf loss, most pre heading insecticide applications should be able to be eliminated in Minnesota without yield losses.


Sewage Sludge Application Linked To Increase In Eastern Tent Caterpillar Populations (Lepidoptera: Lasiocampidae), Louis F. Wilson, John H. Cooley, William J. Mattson Jul 2025

Sewage Sludge Application Linked To Increase In Eastern Tent Caterpillar Populations (Lepidoptera: Lasiocampidae), Louis F. Wilson, John H. Cooley, William J. Mattson

The Great Lakes Entomologist

Numbers of Malacosoma americanum caterpillar tents were positively correlated with average numbers and biomass of cherry trees as well as with amount of sludge applied. The enhancing effect of sewage sludge on amounts of black cherry biomass and foliar nitrogen may have been the principal factors leading to higher tent caterpillar populations on fertilized plots.

Observations On The Nesting And Unique Cachement Behavior Of Calicurgus Hyalinatus (Hymenoptera: Pompilidae), Frank E. Kurczewski, Margery G. Spofford Jul 2025

Observations On The Nesting And Unique Cachement Behavior Of Calicurgus Hyalinatus (Hymenoptera: Pompilidae), Frank E. Kurczewski, Margery G. Spofford

The Great Lakes Entomologist

The components of the nesting and provisioning behavior of Calicurgus hyalinatus are delineated chronologically. The unique cachement of the prey, whereby the spider is suspended from vegetation by its own silken threads, is described. The nesting and provisioning components we observed are compared with those described in the Nearctic and Palearctic literature.


Cleptes Speciosus In The Great Lakes Region (Hymenoptera: Chrysididae: Cleptinae), Mark F. O'Brien Jul 2025

Cleptes Speciosus In The Great Lakes Region (Hymenoptera: Chrysididae: Cleptinae), Mark F. O'Brien

The Great Lakes Entomologist

Cleptes (Melanocleptes) speciosus Aaron is newly recorded from Michigan, with records from five counties in the Upper and Lower peninsulas. A New York record from near Lake Ontario suggests this western species also has a Great Lakes distribution.


Nearctic Epiblema: A New Synonymy, A Revised Identity, And Two New Species (Lepidoptera: Tortricidae), William E. Miller Jul 2025

Nearctic Epiblema: A New Synonymy, A Revised Identity, And Two New Species (Lepidoptera: Tortricidae), William E. Miller

The Great Lakes Entomologist

New findings are reported for four species: Epiblema naoma Clarke is a junior synonym of E. iowana McDunnough; E. numerosana (Zeller) is currently misidentified; E. chromata, currently identified as the preceding, is described from Texas and differentiated from E. grossbecki Heinrich by maculation and female genitalia; and E. arctica, recently discovered in the Alaskan tundra, is described and differentiated from the boreal E. lyallana McDunnough by maculation and male genitalia.


Winter Wheat Cold Hardiness And Fructan Reserves Affected By Rhopalosiphum Padi (Homoptera: Aphididae) Feeding, S. G. Wellso, C. R. Olien, R. P. Hoxie Jul 2025

Winter Wheat Cold Hardiness And Fructan Reserves Affected By Rhopalosiphum Padi (Homoptera: Aphididae) Feeding, S. G. Wellso, C. R. Olien, R. P. Hoxie

The Great Lakes Entomologist

The cold hardiness of 'Winoka' and 'Genesee' winter wheats was each significantly less (P = 0.05) when fed upon by bird-cherry oat aphids, Rhopalosiphum padi, than non-infested seedlings. Aphid feeding also reduced the amount of fructans in crown tissue ca. 20% compared to extracts from crowns of non-infested seedlings. It appears that the cold hardiness of these wheat cultivars may have been reduced because of fructan depletion by insect feeding.


Control Of Hyadaphis Tataricae (Homoptera: Aphididae) On Honeysuckle Including Observations On Host Plant Resistance, Philip L. Nixon, Carolyn Peet Nixon, James E. Schuster Jul 2025

Control Of Hyadaphis Tataricae (Homoptera: Aphididae) On Honeysuckle Including Observations On Host Plant Resistance, Philip L. Nixon, Carolyn Peet Nixon, James E. Schuster

The Great Lakes Entomologist

llyadaphis tataricae causes witches-brooming to the growing tips of Zabelii and other large bush-type honeysuckles in the north central states. Insecticide tests show that acephate (Orthene), dimethoate (Cygan), or oxydemeton-methyl (Metasystox-R) sprayed monthly in June and July will reduce witches-brooming. Malathion was not effective in reducing damage. Host plant resistance observations indicate that Lonicera x notha, L. x muendeniensis, L. x amoena 'Alba', L. x ).;ylosteoides, and L. tatarica 'Arnold Red' are ll. tataricae resistant. These large bush-type honeysuckles would appear to be good replacements for Zabelii and other susceptible honeysuckles in ornamental plantings.


Vulnerability Of Hybrid Populus Nursery Stock To Injury By The Tarnished Plant Bug, Lygus Lineolaris (Hemiptera: Miridae), Louis F. Wilson, Lincoln M. Moore Jul 2025

Vulnerability Of Hybrid Populus Nursery Stock To Injury By The Tarnished Plant Bug, Lygus Lineolaris (Hemiptera: Miridae), Louis F. Wilson, Lincoln M. Moore

The Great Lakes Entomologist

The tarnished plant bug injured 21 Populus clones in the clonal nursery of the Packaging Corporation of America in Michigan. Degree of injury ranged from 0.5 to 81.09<. Clone 'Wisconsin 5' sustained the heaviest attack, followed by Imperial Carolina poplar. 'Wisconsin 5' was salvaged by changing the standard and accepting shorter cutting stock for outplanting.


Interspecific Interactions Between Orchelimum Nigripes And Orchelimum Volantum (Orthoptera: Tettigoniidae), Marianne Niedzlek Feaver Jul 2025

Interspecific Interactions Between Orchelimum Nigripes And Orchelimum Volantum (Orthoptera: Tettigoniidae), Marianne Niedzlek Feaver

The Great Lakes Entomologist

[Excerpt] Interspecific interactions are relatively rare among coinhabiting Orthoptera. Most records are of overzealous males courting females not of their species or, for that matter, inanimate objects. Less frequent are reports of two signalling males interacting, yet these are of interest. Calling songs are used to distinguish species (Alexander 1956). The possibility then exists that the "interference" or, more correctly, the competition for broadcast space that occurs when two closely related species with similar songs interact, may have been influential in shaping aspects of song delivery or pattern.
