New state record and range extension for Mycterus youngi Pollock (Coleoptera: Mycteridae) – but is it really rare?

Mycterus youngi was described from Wisconsin and “L.S” (presumed to indicate along Lake Superior). All but one of the specimens in the type series were collected between 1947 and 1949. Herein, three females of M. youngi are reported from Michigan, between 1910 and 1940. A discussion of possible implications of the few, and largely old collection dates is provided

The Occurrence of \u3ci\u3eDitylus Caeruleus\u3c/i\u3e in Michigan (Coleoptera: Oedemeridae), With Observations on Its Range

The oedemerid beetle, Ditylus caeruleus, is recorded for the first time from Mar- quette County, Michigan. Bionomical data associated with the specimens represent the first such information for this species. Eight additional new Michigan county records for the species are also reported, including the first specimens from the Lower Peninsula. The distributional range of caeruleus is highly correlated with the Great Lakes, the 81. Lawrence River, and coastal Maine. Implications of this distribution pattern relating to possible development of larvae in driftwood and the potential significance of rafting as a dispersal mechanism are also discussed

Cantharidin and Insects: An Historical Review

The defensive role played by cantharidin in meloid and oedemerid beetles has been well documented. However. several groups of insects are known to orient positively toward the chemical or to the beetles which produce it: Miridae (Hemiptera); Pyrochroidae, Anthicidae (Coleoptera): Ceratopogonidae, Anthomyiidae (Diptera); and Braconidae Hymenopteran. Literature citations are summarized for each of these taxa using current nomencla.tun: and indicating the nature of the association

Field Records and Observations of Insects Associated With Cantharidin

This paper reports on insect species not previously associated with cantharidin, the terpenoid defense mechanism of blister beetles (Meloidae). Species from the following tau were obserYed and collected: Miridae (Hemiptera); Endomychidae, Pyrochroidae, AnthiLidae (Coleoptera); Ceratopogonidae, Sciaridae (Diptera); and Braconidae (Hymenoptera). In addition to listing the associations, a discussion of cantharidin orientation is presented along with preliminary hypotheses to explain these intriguing examples of coevolution

Description of the Larva of \u3ci\u3eDioedus Punctatus\u3c/i\u3e LeConte (Coleoptera: Tenebrionidae)

Larvae of Dioedus punctatus LeConte have been collected from logs, probably Ulmus americana, in the red-rotten stage of decay and determined from reared adults. They are described and illustrated

Distribution of \u3ci\u3ePelecinus Polyturator\u3c/i\u3e in Wisconsin (Hymenoptera: Pelecinidae), With Speculations Regarding Geographical Parthenogenesis

The geographical distribution of Pelecinus polyturator in Wisconsin is summarized. Only five males have been recorded; a recently collected male from the University of Wisconsin Field Station in Ozaukee County represents the first male collected in the state in over 40 years. Speculations on the possible significance and implications of geographical parthenogenesis relative to Pelecinus are offered

(excerpt) Those of you who know me may think I’ve always been a “beetle guy” but growing up in southwestern Michigan and loving to trout fish, my first real insect infatuation was with aquatic insects. It was, in fact, not until the summer of my junior/senior year at Michigan State University that I was re- ally introduced to beetles – by a Ph.D. student for whom I worked as a student hourly (on cucumber pollination and honey bees)

A New Prey Record for \u3ci\u3eCerceris Fumipennis\u3c/i\u3e Say (Hymenoptera: Sphecidae: Cercerini)

(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

Field Studies of Cantharidin Orientation by \u3ci\u3eNeopyrochroa Flabellata\u3c/i\u3e (Coleoptera: Pyrochroidae)

During field studies conducted in south-central Michigan in 1977 and 1980. 109 specimens of Neopyrochroa flabellata were observed and collected at filter papers baited with cantharidin. Only the two highest concentrations used (39.2 mg. 392 j.Lg) elicited responses. and the beetles did not prefer one over the other. In the 24-h studies, most specimens were observed at the cantharidin baits between dusk and 0100 hrs (61 %; n = 14). and 0430-0630 hrs (26%; n = 6). Only two of the 109 specimens were female
