Observations On Colony Size In Bumblebees (Bombus Spp.), Robert W. Husband

The Great Lakes Entomologist

(excerpt)

One factor to consider when attempting to rear bumblebees (Bombus spp.) for pollination of crops is potential colony size. Species which emerge from hibernation early and continue to produce workers late in the summer or early fall are likely to have larger colonies. In contrast, Arctic species such as Bombus polaris Curtis and hyperboreus Schonherr may produce only one brood prior to the sexual brood. Richards (1973) reported that colonies of polaris are smaller than colonies of species from lower latitudes in North America. Hobbs (1967) estimated 772 as a maximum colony sue for huntii Greene in southern …

A New Genus And Species Of Isotomidae (Collembola), And A Redescription Of Cryptopygus Exilus (Gisin) N. Comb, E. C. Bernard

The Great Lakes Entomologist

A new genus and species of Collembola in the family lsotomidae are described from Michigan: Micranurophorus musci n. g., n. sp. A redescription of Cryptopygus exilis (Gisin) (= Isotomina exilis Gisin) is also given, based on specimens from Michigan. The new genus is characterized by the lack of a furcula and by abdominal chaetotaxy similar to Isotomodes. It is related to Pseudanurophorus.

The Great Lakes Entomologist

(excerpt)

John Robert Eyer died at Carlsbad, New Mexico, on January 30, 1976. J. G. Watts and W. A. Iselin (1976), his former colleagues in the Department of Botany and Entomology at New Mexico State University, Las Cruces, wrote an obituary and quite naturally focused on Eyer's work at the University's Agricultural Experiment Station. Since Dr. Eyer's first positions in entomology were in Pennsylvania, we have prepared this biographical sketch to preserve the record of his early accomplishments.

On The Occurrence Of Oarisma Garita (Reakirt) (Lepidoptera: Hesperiidae) In Manitoulin District, Ontario, Paul M. Catling

The Great Lakes Entomologist

(excerpt)

On 26 June, 1976, I stopped to examine plants and collect insects on the alvars or limestone barrens on Great La Cloche Island, north of Little Current in Manitoulin District, Ontario. 1 was especially interested to learn whether or not there were any insects of western affinity in this area since some of the plant species present are at, or near to, the eastern limits of their distribution (Catling et al., 1975). It was mild and sunny, and insects were abundant. Within a few minutes 1 noticed a dark, fast-flying skipper that otherwise resembled Thymeliczrs lineola (Ochsenheimer). The dark …

Intraspecific Variation In Taxonomic Characteristics Of The Mayfly Potamanthus Myops (Walsh), Robert J. Lord, Peter G. Meier

The Great Lakes Entomologist

Data collected from an ecological study of the mayfly Potamanthus rnyops (Walsh) in Michigan showed intraspecific variability in taxonomic characteristics that have been employed by previous investigators for species separation. Nymphal dorsal maculation patterns varied considerably within a single population. Also, the ratio of mandibular tusk length to head length increased with successive nymphal instars. Certain adult taxonomic characteristics, particularly relative male imago eye size and distance of separation, were either too poorly defined or too variable to be conclusive in species identification.

Weights Of Polia Grandis Pupae Reared At Two Constant Temperatures (Lepidoptera: Noctuidae), William E. Miller

The Great Lakes Entomologist

Sibling Polia grandis (Boisduval) larvae were reared at two constant temperatures on fresh foliage of quaking aspen (Populus tvemuloides Michx.). Female pupae developing at 25°C were 24% heavier than those developing at 30°C and corresponding males were 32% heavier. Duration of the larval period averaged 51 days at the former temperature and 41 days at the latter. Based on other Lepidoptera, a 24% change in pupal weight affects fecundity by 28 to 130 eggs per female. Fluctuations in larval temperature regime might induce size and fecundity variation in natural populations of grandis and other Lepidoptera.

The Distribution Of Corydalus Cornutus (Linnaeus) And Nigronia Serricornis (Say) (Megaloptera: Corydalidae) In Michigan, Allen W. Knight, Clifford A. Siegfried

The Great Lakes Entomologist

(excerpt)

The distribution of the hellgrammite [Corydalus cornutus (Linnaeus)] and the sawcombed fishfly [Nigronia serricornis (Say)] in Michigan was determined as part of an investigation of the biology of these large Megalopterans (Knight and Simmons, 1975a, 1975b). Megalopteran larvae are some of the largest aquatic insects, with a maximum length of approximately 84 mm. They are robust larvae with paired lateral abdominal appendages on segments 1-8 and a pair of anal prolegs bearing two strong hooks. They are fiercely predaceous and generally insectivorous, feeding chiefly on larvae of Simulium, Cheumatopsyche, Hydropsyche and Chironomidae, but eating almost anything they can subdue, …

An Annotated List Of The Cerambycidae Of Michigan (Coleoptera) Part Ii, The Subfamilies Lepturinae And Lamiinae, D.C. L. Gosling, N. M. Gosling

The Great Lakes Entomologist

(excerpt)

This is a continuation of Part I of an annotated list of the Cerambycidae known from Michigan, and includes the remaining subfamilies Lepturinae and Lamiinae. The format is similar to that used in Part I. We have largely followed the systematic order of Chemsak and Linsley (1975) in this part of the list. Keys for the identification of adult Lepturinae can be found in Linsley and Chemsak (1972; in press). References to keys for adult Lamiinae are listed under that subfamily. Many larvae may be identified through the keys in Craighead (1923), but not all Michigan species are covered

The Great Lakes Entomologist

(excerpt)

The continuing demand for general references and aids to identification of Ephemeroptera has undoubtedly prompted the recent reprinting of The Mayflies. . . of Illinois. A two-page preface by George F. Edmunds, Jr. dealing with taxonomic and nomenclatural changes since the original 1953 publication has been added and will serve as an adequate aid to those unfamiliar with changing concepts in mayfly systematics. The reprinting is of high quality with the large number of figures having been excellently reproduced in this hard-bound edition.

This little book will undoubtedly please the amateur collector and rearer of the exotically and exquisitely colored species such as found in the Saturniidae and Sphing- idae. Of the 103 colored photographic plates, 69 illustrate species from these two popular families. Each species is figured on a white background in sharp and vivid color. One species is figured on a page, except for Epicopeia polydora, which includes a figure of its mimetic model Papilio rhetenor.

Mites Of Moths And Butterflies, Asher Treat. Cornell University Press, 1975. $35.00., Robert W. Husband

The Great Lakes Entomologist

(excerpt)

Don't let the price tag frighten you. This is a book you will turn to again and again, in fact every time you pick up a moth or butterfly and wonder if it is one of those on which Asher Treat found mites. The quotation on the fly leaf gives an insight into the enthusiasm and curiosity, as well as the thoroughness of Asher Treat. "Whether in the field, at home, or in a museum collection, the search for mites on insect hosts is an adventure as exciting as any treasure hunt. Every insect, looked at closely enough to …

Les Carabidae Du Quebec Et Du Labrador. Andre Larochelle, Dept. De Biologie Du College Bourget, Rigaud, Quebec. Bull. 1:1-255. 1975. $15.00 Canadian., James Liebherr

The Great Lakes Entomologist

(excerpt)

This work is advertised as a catalog of the Carabidae of Quebec, with annotations concerning distribution and bionomics of the various Quebec species. Mr. Larochelle's long range plan is aimed at a complete study of "the ecology, the biology, and the dynamics of those marvelous insects." This, therefore, appears to be the first part of a set of papers similar to Carl Lindroth's studies of Newfoundland carabids (Lindroth, 1955, 1963).

Erynnis Funeralis (Lepidoptera: Hesperiidae) And Polygonia Zephyrus (Lepidoptera: Nymphalidae) In Indiana: New State Records, Ernest M. Shull

The Great Lakes Entomologist

(excerpt)

On July 1, 1975, while collecting 18 Pieris napi oleraceal (Harris) in the famous tamarack bog near Mongo, LaGrange Co., Indiana, I collected a somewhat worn male Erynnis funeralis Scudder & Burgess when it was resting on the ground in an area between the bog and a woods.

A New Prey Record For Cerceris Fumipennis Say (Hymenoptera: Sphecidae: Cercerini), Daniel K. Young

The Great Lakes Entomologist

(excerpt)

The sphecid wasp tribe Cercerini is comprised of the genera Cerceris and Eucerceris, the former being widely distributed and the latter restricted to North America All species of Eucerceris for which prey records have been determined utilize snout beetles or weevils (Curculionidae) to feed the young. In North America, known prey records for Cerceris include members of the beetle families Buprestidae, Tenebrionidae, Chrysome- lidae, Bruchidae, and Curculionidae. Some European members of the genus have been

reported to provision the nests with other hymenopterans (e.g. solitary bees of the families Halictidae and Andrenidae) in addition to beetles.

Anaphes (Hymenoptera: Mymaridae) Reared From The Eggs Of A Shore Fly (Diptera: Ephydridae), R. W. Thier, Richard S. Zack, B. A. Foote

The Great Lakes Entomologist

Members of the family Mymaridae are obligate parasitoids of insect eggs, and some species attack the eggs of aquatic insects. Only one account of egg parasitism by the mymarid genus Anaphes on Diptera has been disclosed in the literature. Bakkendorf (1971) bred Anaphes autumnalis Foerster from an egg of Tipula autumnalis Loew.

A Possible Case Of Spatial Isolation In Brine Flies Of The Genus Ephydra (Diptera: Ephydridae), Richard S. Zack, R. W. Thier, B. A. Foote

The Great Lakes Entomologist

(excerpt)

During the summer of 1975, adults and larvae of Ephydra riparia Fallen and E. cinerea Jones were encountered in the many brine pools occurring on the property of the Morton Salt Company at Rittman, Wayne County, Ohio (Scheiring and Foote, 1973). Larvae of both species have been reported to be salt tolerant (Bayly, 1972). E. ripariu larvae can survive in salinities up to 80°/oo (Sutcliffe, 1960), and the larvae of cinerea have been encountered by Nemenz (1960) in the Great Salt Lake of Utah at a salinity of 300°/oo.
