Major Northeastward Range Extension For A Western Grasshopper Species: New State Record For Trimerotropis Pallidipennis (Burmeister) In Wisconsin, Mathew L. Brust

The Great Lakes Entomologist

Trimerotropis pallidipennis (Burmeister) mostly occurs in the southwestern U.S., but is known to migrate significant distances periodically. It appears that some individuals of this species occasionally migrate very long distances. Here I present an extreme record for this species, over 480 km northeast of any previously known records, including any others recorded from 2022. A single male specimen was collected and photographed in Price County in north-central Wisconsin in June 2022.

Two New Coleopteran Records From Wisconsin, Jordan D. Marche Ii

The Great Lakes Entomologist

Specimens of two different species of beetles, representing that many separate families of Coleoptera, are herein reported as new to Wisconsin. These species occur respectively within the following families: Zopheridae and Trogossitidae.

Rediscovery Of Gnoriste Macra Johannsen In Wisconsin (Diptera: Mycetophilidae: Gnoristinae), Daniel K. Young

The Great Lakes Entomologist

Gnoriste macra Johannsen was described from Whitefish Bay, Wisconsin in 1912. The type locality is now a highly residential region a few miles north of the center of Milwaukee. Herein, collection events are reported for G. macra from Sauk County in southcentral Wisconsin. These new records, nearly a century after the only other literature record, indicate the species still thrives in Wisconsin though likely extirpated from the type locality. The specimens were recovered from unbaited Townes Malaise traps during mid- to late May, 2006 and 2020. Cranial anatomy and functional morphology of the head suggests G. macra may be a …

New Record Of Idana Marginata (Say) (Diptera: Tephritoidea: Ulidiidae) From Wisconsin, Daniel K. Young

The Great Lakes Entomologist

Idana marginata (Say) was previously known from northeastern North America: Canada and the United States, west to northeastern Illinois and south to North Carolina. Herein, collection events are reported from Richland County in southwestern Wisconsin. This new state record significantly increases the known geographical distribution of the species to the west. The specimens were recovered from an unbaited Lindgren funnel trap during two intervals between 26 June and 28 July 2019.

Further New Records Of Coleoptera And Other Insects From Wisconsin, Jordan D. Marche Ii

The Great Lakes Entomologist

Specimens of eleven different species of insects, representing seven separate families of Coleoptera, and one family each of Hemiptera, Lepidoptera, Diptera, and Hymenoptera, are herein reported as new to Wisconsin. These genera or species occur respectively within the following families: Leiodidae, Monotomidae, Cucujidae, Cryptophagidae, Ciidae, Tetratomidae, Curculionidae, Pentatomidae, Glyphipterigidae, Phoridae, and Pteromalidae. All but one of these insects were collected at or near the author’s residence (Dane County); the pentatomid was taken in northern Wisconsin (Oconto County). Three of the four non-coleopteran fauna are introduced species.

Parasitism Of Female Neotibicen Linnei (Hemiptera: Cicadidae) By Larvae Of The Sarcophagid Fly Emblemasoma Erro In Wisconsin, Allen M. Young

The Great Lakes Entomologist

Herein it is reported an unusual case of parasitism of a female Neotibicen linnei (Smith and Grossbeck) by the sarcophagid Emblemasoma erro (Aldrich) in western Wisconsin. Sarcophagids typically attack male cicadas, locating them by the latter’s acoustical behavior.

Some members of the dipteran family Sarcophagidae are parasitic on male cicadas (e.g. Soper et. al. 1976, Lakes-Harlan et. al. 2000, Faris et. al. 2008, Stucky 2015). Parasitoids such as Emblemasoma species are attracted to larviposit on male cicadas by responding to the latter’s acoustical signals (Tron et. al. 2016). Sarcophagids, therefore, are generally not attracted to mute female cicadas. In this …

Dragonfly (Odonata: Corduliidae, Macromiidae, Gomphidae, Aeshnidae) And Damselfly (Odonata: Calopterygidae) Exuviae Observed At Record Heights In Pinus Strobus And Picea Abies Canopies, Madison M. Laughlin, Jonathan G. Martin, Patrick J. Liesch, Erik R. Olson

The Great Lakes Entomologist

Most odonate species do not typically climb higher than 50 cm when choosing an emergence support. We observed multiple species of odonate nymphs using trees as emergence supports at heights greater than 50 cm and up to 4, 6.9, and 14.6 m for Calopteryx maculata (Ebony Jewelwing), Somatochlora minor (Ocellated Emerald), and Didymops transversa (Stream Cruiser), respectively. These heights represent the greatest heights ever documented for odonate nymphs emergence supports. Our research suggests that some species (S. minor; D. transversa) appear to have a greater affinity for climbing to great heights during emergence than others (Dromogomphus spinosus …

New Species Records For Wisconsin False Click Beetles (Coleoptera: Eucnemidae),, Robert L. Otto, Daniel K. Young

The Great Lakes Entomologist

In Wisconsin, Microrhagus opacus, Euryptychus ulkei and Fornax bicolor are recorded for the first time. Records for these three species are based on nine specimens, most of which were taken since 2008. Two specimens of M. opacus taken from a Grant County Malaise trap in the late 1970’s as part of a statewide gypsy moth parasitoid recovery project, were previously identified as Microrhagus audax. Most of the specimens reported herein were taken late in the collecting season, primarily during August. A checklist of the 20 genera and 41 species of Wisconsin Eucnemidae is also included.

Species And Life Stages Of Odonata Nymphs Sampled With Large Drift Nets In Two Wisconsin Rivers, Bob Dubois, Dennis Pratt

The Great Lakes Entomologist

Because relatively few nymphs of Odonata are caught in most drift studies, they have been inconsistently reported and little is known about the species and life stages that are predisposed to drift. We used large drift nets with relatively coarse mesh sizes (1500 µm) to sample late-instar odonate nymphs in two large rivers in Wisconsin. These nets were presumed to have advantages over smaller, conventional aquatic insect drift nets, including the capability to sample greater water volumes more quickly, sampling for longer periods of time before nets become clogged with debris, and a reduced likelihood of large, active insects …
