Major Northeastward Range Extension For A Western Grasshopper Species: New State Record For Trimerotropis Pallidipennis (Burmeister) In Wisconsin, Mathew L. Brust Mar 2024

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.


Adult Neurocolpus Nubilus And Plagiognathus Sp. Dispersal On Tropaeolum Majus, Elyse Malamud Mar 2024

Adult Neurocolpus Nubilus And Plagiognathus Sp. Dispersal On Tropaeolum Majus, Elyse Malamud

The Great Lakes Entomologist

Neurocolpus nubilus (Say) (Hemiptera: Miridae), commonly known as the clouded plant bug, is a species of plant bug. Widespread primarily across eastern North America, N. nubilus is known to feed on many types of plants. At least 43 host plants spanning 34 plant families have been recorded for N. nubilus and more may be possible. Plagiognathus (Fieber) (Hemiptera: Miridae) is a genus of plant bugs that is widespread across the Holarctic region. Plagiognathus spp. are typically found on various woody host plants. This paper describes an instance of adult N. nubilus and Plagiognathus sp. feeding on a cultivar of Tropaeolum …


First Known Records Of The Specialist Bee, Colletes Aestivalis (Hymenoptera: Colletidae), In An Urban Area, Nina S. Fogel, Christine Kirmaier, Mike Arduser Mar 2024

First Known Records Of The Specialist Bee, Colletes Aestivalis (Hymenoptera: Colletidae), In An Urban Area, Nina S. Fogel, Christine Kirmaier, Mike Arduser

The Great Lakes Entomologist

Here we report on the first known records of the Heuchera specialist bee Colletes aestivalis in an urban area. This bee was found by a participant in a citizen science project in a residential garden in a suburb that abuts St. Louis, Missouri. The females were found only visiting Heuchera richardsonii, and the males were seen scouting for females by hovering over the plants. This finding shows that urban areas can support uncommon specialist bees and the utility of engaging non-experts in cataloging biodiversity.


Willow Pollen Collection By A Blueberry Specialist Bee (Hymenoptera: Andrenidae), James B. Watson, Keziah G. Bartel, Jason Gibbs Mar 2024

Willow Pollen Collection By A Blueberry Specialist Bee (Hymenoptera: Andrenidae), James B. Watson, Keziah G. Bartel, Jason Gibbs

The Great Lakes Entomologist

Andrena (Conandrena) bradleyi Viereck (Hymenoptera: Andrenidae) is widely regarded as a Ericaceae specialist bee due to its elongate head, plant records, and common collection in commercial blueberry fields. We provide evidence of A. bradleyi collecting pollen from willow (Salix, Salicaceae) L. in southeastern Manitoba. This indicates the bee is not obligately specialized on Ericaceae pollens and that early blooming plants may contribute to its early nutritional requirements.


Evidence Of Lilac Borer (Lepidoptera: Sesiidae) Population On Mackinac Island, Mi, David Max Lowenstein Mar 2024

Evidence Of Lilac Borer (Lepidoptera: Sesiidae) Population On Mackinac Island, Mi, David Max Lowenstein

The Great Lakes Entomologist

Mackinac Island, Michigan, is a major tourism destination with its lilacs an important part of the local culture. Recently, the health of some lilacs has declined. It is uncertain if this is due to the lilac’s age, attack by lilac borer, Podosesia syringae (Harris) (Lepidoptera: Sesiidae), or a combination of environmental and biotic factors. The lilac borer is a clearwing moth whose larvae bore within ash and lilac, and there are minimal local records of the insect in Northern Michigan and none on Mackinac Island. This study deployed pheromone traps to identify the flight period of lilac borer, potential damage …


New Record Of The Pavement Ant, Tetramorium Immigrans (Hymenoptera: Formicidae), In South Dakota With Notes On Its Thermal Tolerance And Geographic Distribution, Karl A. Roeder, Skylar Drey, Jesse D. Daniels, Diane V. Roeder, Jackson A. Helms Iv Mar 2024

New Record Of The Pavement Ant, Tetramorium Immigrans (Hymenoptera: Formicidae), In South Dakota With Notes On Its Thermal Tolerance And Geographic Distribution, Karl A. Roeder, Skylar Drey, Jesse D. Daniels, Diane V. Roeder, Jackson A. Helms Iv

The Great Lakes Entomologist

The pavement ant, Tetramorium immigrans, is an abundant and widespread species across large portions of the United States. Yet despite its current distribution in Northeastern, Midwestern, Pacific, and Western states, there is a surprising lack of records from the Great Plains. Here we present an updated county list of T. immigrans from museum collections and research grade observations (459 counties; ~15% of US counties), highlighting the first records from one Great Plains state—South Dakota. Observations on community science platforms since 2006 have undoubtedly increased the awareness of T. immigrans (+329 counties; ~72% of all county records), however we posit …


Bee (Hymenoptera: Anthophila) Richness In Eastern Ohio Pipeline Right Of Ways, Malisa Spring, Gabriel R. Karns Mar 2024

Bee (Hymenoptera: Anthophila) Richness In Eastern Ohio Pipeline Right Of Ways, Malisa Spring, Gabriel R. Karns

The Great Lakes Entomologist

It is relatively unknown which species of bees utilize pipeline Right of Ways. Most recent Right of Way research focuses on bees found on electrical transmission Right of Ways instead. Ohio is also relatively understudied in terms of bee richness. This project sought to document bees that are found in these pipeline Right of Ways in 4 heavily forested counties in eastern Ohio. A total of 3950 specimens were collected, accounting for 140 species across two years of sampling (2016 and 2018). Overall bee abundance peaked mid-season, with the highest abundance observed in July. The majority of bees collected were …


Reevaluating Abrupt Biological Discontinuity In A Small Michigan (Usa) Stream – Differences In The Organic Biomass Of Aquatic Macroinvertebrate Functional Feeding Groups Based On Benthic And Terrestrial Habitat, David C. Houghton, Danae Sollie, Daniel Votel, Elizabeth Potwardowski Mar 2024

Reevaluating Abrupt Biological Discontinuity In A Small Michigan (Usa) Stream – Differences In The Organic Biomass Of Aquatic Macroinvertebrate Functional Feeding Groups Based On Benthic And Terrestrial Habitat, David C. Houghton, Danae Sollie, Daniel Votel, Elizabeth Potwardowski

The Great Lakes Entomologist

To examine the effects of habitat and benthic substrate differences on macroinvertebrate assemblages along a single continuum, we tested three sites along a small northern Lower Michigan stream over a four-year period. Terrestrial habitat along the stream abruptly changed from a cedar forest, to an open meadow, to a hardwood forest within a 1.4 km reach. Reflecting these changes, overhead canopy coverage and in-stream woody debris were higher at the two forested sites, whereas the organic biomass of periphyton was higher at the meadow site. The meadow site also had faster stream velocity and a greater volume of coarse benthic …


Observations On A Dendroctonus Simplex (Coleoptera: Curculionidae: Scolytinae) Outbreak In A Rangewide Tamarack (Larix Laricina) Provenance Plantation In Michigan, Robert A. Haack, Richard W. Blank Mar 2024

Observations On A Dendroctonus Simplex (Coleoptera: Curculionidae: Scolytinae) Outbreak In A Rangewide Tamarack (Larix Laricina) Provenance Plantation In Michigan, Robert A. Haack, Richard W. Blank

The Great Lakes Entomologist

A tamarack [Larix laricina (Du Roi) K. Koch] provenance plantation, consisting of 33 seed sources from the United States and Canada, was established in 1969 in southern Michigan (Kalamazoo County). About half of the trees were removed in fall 1984 when the stand was thinned, with the cut trees piled on the edge of the stand. The stand then experienced a severe ice storm in January 1985. The eastern larch beetle, Dendroctonus simplex LeConte, colonized the cut logs in 1985 and also infested many of the standing trees. By the end of 1986, over half the remaining trees had …


Observations On The Oak Twig Pruner, Anelaphus Villosus (Coleoptera: Cerambycidae), In Michigan: Size Of Twigs Pruned, Insect Survival, And Seasonality Of Twig Drop, Robert A. Haack Mar 2024

Observations On The Oak Twig Pruner, Anelaphus Villosus (Coleoptera: Cerambycidae), In Michigan: Size Of Twigs Pruned, Insect Survival, And Seasonality Of Twig Drop, Robert A. Haack

The Great Lakes Entomologist

The oak twig pruner [OTP; Anelaphus villosus (Fabricius)] is likely a species complex, with A. parallelus (Newman) recently recognized as a synonym. The parallelus form of A. villosus is considered the subject of this paper. In Michigan, OTP has a 2-year life cycle, with twigs pruned primarily in even-numbered years and adults emerging from the fallen twigs in odd-numbered years. During 1990 to 2011, I studied various aspects of OTP life history in southern Michigan (Ingham County). Based on measurements from over 300 infested oak twigs, they averaged 43.1 cm long, 9.4 mm in diameter at the pruned end, …


Flies Associated With Floral Canopies Of The New Oilseed Crop, Pennycress, In The Midwestern U.S.A., Frank Forcella, Matt Petersen, William L. Perry, Samantha S. Wells, Alex Hard, Russ W. Gesch, Yesuf Mohammed, Cody Hoerning, Tad L. Wesley, Emma Ambrosi, Winthrop B. Phippen Mar 2024

Flies Associated With Floral Canopies Of The New Oilseed Crop, Pennycress, In The Midwestern U.S.A., Frank Forcella, Matt Petersen, William L. Perry, Samantha S. Wells, Alex Hard, Russ W. Gesch, Yesuf Mohammed, Cody Hoerning, Tad L. Wesley, Emma Ambrosi, Winthrop B. Phippen

The Great Lakes Entomologist

Flies are frequent visitors to flowers of many species of plants within the mustard family (Brassicaceae). They derive nutrition from these flowers, and some fly species are pollinators. Field pennycress (Thlaspi arvense) is a mustard species that is being developed as a new “cash cover crop,” i.e., an autumn-sown cover crop whose oil-rich seeds can be harvested profitably in spring. Although pennycress is largely wind- and self-pollinated, its flowers also attract insect visitors. However, the extent of visitation to pennycress flowers by flies remains largely unknown, especially the identities of those flies. Thus, we examined flies associated with …


The Heteroptera (Hemiptera) Of North Dakota Ii: Enicocephalomorpha : Enicocephalidae, Alexander H. Knudson, Veronica Calles Torrez, David A. Rider Mar 2024

The Heteroptera (Hemiptera) Of North Dakota Ii: Enicocephalomorpha : Enicocephalidae, Alexander H. Knudson, Veronica Calles Torrez, David A. Rider

The Great Lakes Entomologist

The Enicocephalomorpha of North Dakota is documented with the report of the unique-headed bug, Systelloderes biceps (Say, 1832) from North Dakota for the first time. We also discuss the geographic distribution of S. biceps and Systelloderes culicis (Uhler, 1892), provide color photographs, provide diagnoses for the separation of these species from all other North American species, and designate a lectotype for S. culicis (Uhler).

The Recently-Described Ant-Like Leaf Beetle Elonus Gruberi (Coleoptera: Aderidae) In Michigan, Daniel R. Swanson Sep 2023

The Recently-Described Ant-Like Leaf Beetle Elonus Gruberi (Coleoptera: Aderidae) In Michigan, Daniel R. Swanson

The Great Lakes Entomologist

The ant-like leaf beetle Elonus gruberi Gompel, 2017 (Coleoptera: Aderidae) is reported for the first time in Michigan. This new state record, initially based on two recent collections by the author and then supplemented with additional material in a Michigan entomological collection, highlights how the constituents of faunal lists can require re-appraisal after taxonomic revision, particularly where splitting of species has occurred. The composition of Elonus Casey, 1895 in Michigan as well as characters for identifying E. gruberi also are discussed.


First Records Of Three Carpophilinae (Coleoptera: Nitidulidae) In Quebec, Ludovic Leclerc, Pierrick Bloin, Françoise Pelletier, Christian Hébert, Kishan Sambaraju Sep 2023

First Records Of Three Carpophilinae (Coleoptera: Nitidulidae) In Quebec, Ludovic Leclerc, Pierrick Bloin, Françoise Pelletier, Christian Hébert, Kishan Sambaraju

The Great Lakes Entomologist

We report first records for three species of Carpophilinae (Coleoptera: Nitidulidae), two for the province of Quebec (Caplothorax lugubris and Carpophilus corticinus), a third species (Carpophilus marginatus) being a first report for Canada. These beetles were trapped while conducting population assessments of oak wilt vectors and in amateur collections. Biological information and a brief description of the records including distribution data in Quebec for the three species are presented.


Four New State Records Of Delphacid Planthopper Species (Hemiptera: Fulgoroidea) From Illinois, Usa, Morgan E. Brown, Christopher H. Dietrich Sep 2023

Four New State Records Of Delphacid Planthopper Species (Hemiptera: Fulgoroidea) From Illinois, Usa, Morgan E. Brown, Christopher H. Dietrich

The Great Lakes Entomologist

Four planthopper species– Aethodelphax aetocephalus (Beamer 1948), Bakerella cinerea Beamer, 1945, Bakerella minuta Beamer, 1950, and Pissonotus aphidioides Van Duzee, 1897 – are newly recorded from Illinois based on collections obtained in the summers of 2005 and 2022. Specimens were collected via net-sweeping and vacuuming of herbaceous vegetation and identified using external morphology and male genitalia morphology. Locality and collection data for each species are summarized; and relevant taxonomic and ecological information for each species is provided. Photographs of pinned specimens and male genital capsules are also provided. These new records reveal apparently disjunct populations of A. aetocephalus and B. …


Periodical Cicadas (Magicicada Spp.): Predator Satiation, Or Too Much Of A Good Thing?, John R. Cooley, Greg Holmes Sep 2023

Periodical Cicadas (Magicicada Spp.): Predator Satiation, Or Too Much Of A Good Thing?, John R. Cooley, Greg Holmes

The Great Lakes Entomologist

We report a novel mode of ecdysis failure in periodical cicadas (Magicicada spp. Davis) tied to the cicadas’ reliance on high densities for survival in the face of predation. Under extremely high densities, cicadas can disrupt others undergoing ecdysis by knocking them loose from their perches, trapping them, or causing physical damage. Our observations raise the possibility that while periodical cicadas thrive at high densities, it is possible that some densities are so high that they inhibit success.


Synopsis Of Biological Control For European Fruit Lecanium (Parthenolecanium Corni) By Parasitoids In North America And Preliminary Findings In Hybrid Hazelnut Orchards, Simone G. Traband, Hailey N. Shanovich, John C. Luhman, Brian Aukema Sep 2023

Synopsis Of Biological Control For European Fruit Lecanium (Parthenolecanium Corni) By Parasitoids In North America And Preliminary Findings In Hybrid Hazelnut Orchards, Simone G. Traband, Hailey N. Shanovich, John C. Luhman, Brian Aukema

The Great Lakes Entomologist

The European fruit lecanium, Parthenolecanium corni (Bouché) (Hemiptera: Coccidae) is a native insect to North America that causes significant damage to a large variety of fruit and ornamental trees worldwide. Here we provide a summary of the insect’s worldwide distribution and synopsis of all the Hymenopteran parasitoid wasps found to parasitize P. corni in North America from past literature. Additionally, a preliminary parasitoid survey of P. corni was carried out in two hybrid hazel (Corylus avellana × C. americana) plantings as hazelnuts represent a potential new crop for the region. European fruit lecanium, Parthenolecanium corni (Bouché) (Hemiptera: Coccidae), were collected …


Abundance And Diversity Of Bees Visiting Flowering Pennycress, A New Oilseed Crop In The Midwestern Usa, Frank Forcella, Zachary M. Portman, Samantha S. Wells, William Perry, Russ W. Gesch, Yesuf Mohammed, Cody Hoerning, Alex Hard, Tad L. Wesley, Winthrop B. Phippen Sep 2023

Abundance And Diversity Of Bees Visiting Flowering Pennycress, A New Oilseed Crop In The Midwestern Usa, Frank Forcella, Zachary M. Portman, Samantha S. Wells, William Perry, Russ W. Gesch, Yesuf Mohammed, Cody Hoerning, Alex Hard, Tad L. Wesley, Winthrop B. Phippen

The Great Lakes Entomologist

Oilseed pennycress (Thlaspi arvense) is a new, autumn-sown, “cash cover crop” for the Midwestern USA and elsewhere. Anthesis occurs in early spring when few other plants bloom, and its flowers attract early-emerging bees. However, the taxonomic composition of these bees was unknown. Consequently, we systematically captured and identified the genera and species of bees visiting pennycress flowers throughout anthesis at five site-years: two in Illinois and three in Minnesota. A cumulative total of 28 bee species were found across site-years. The most common genera were Andrena (10 species), Lasioglossum (12 species), and Halictus (2 species). Rarer genera were …

Limoniic Acid Is A Sex Attractant Pheromone Component Of Limonius Agonus (Coleoptera: Elateridae), Wim Van Herk, Regine Gries, Jocelyn Smith, Ian Scott, Gerhard Gries

The Great Lakes Entomologist

Recently, (E)-4-ethyloct-4-enoic acid (limoniic acid) has been reported as the major sex attractant pheromone component of L. canus and L. californicus (Coleoptera: Elateridae) in western North America. Our objective was to determine whether limoniic acid is also a sex attractant pheromone component of the eastern field wireworm, Limonius agonus (Say). In gas chromatographic-electroantennographic detection (GC-EAD) analyses of headspace volatiles from L. agonus females, antennae from male L. agonus responded to limoniic acid as a trace component. In field experiments, traps baited with synthetic limoniic acid, or its analog (E)-5-ethyloct-4-enoic acid, afforded captures of male L. …

Observations On Two Stem-Boring Coleoptera Of Prickly-Ash (Zanthoxylum Americanum) In Michigan: Micracis Suturalis (Curculionidae: Scolytinae) And Sternidius Alpha (Cerambycidae), Robert A. Haack

The Great Lakes Entomologist

The xylophagous scolytine Micracis suturalis LeConte and the cerambycid beetle Sternidius alpha (Say) were reared or collected from trunk sections of prickly-ash, Zanthoxylum americanum Mill., in Ingham County, Michigan during 1986 to 1988. Most M. suturalis gallery systems were initiated by August in host material cut in late May 1987. Micracis suturalis gallery-system density data are presented. No M. suturalis were reared from caged host material one-year after cutting. Sternidius alpha was univoltine, with adults emerging from mid-May to mid-July from host material cut the previous spring. From 1 to 8 S. alpha larvae originated from individual oviposition sites, averaging …


Alderfly (Megaloptera: Sialidae) Larval Emergence And Pupation Site Selection At Intermediate Lake, Antrim County, Michigan, Robert A. Haack Sep 2023

Alderfly (Megaloptera: Sialidae) Larval Emergence And Pupation Site Selection At Intermediate Lake, Antrim County, Michigan, Robert A. Haack

The Great Lakes Entomologist

Larvae of the alderfly Sialis mohri Ross were collected in barrier pitfall traps along the shoreline of Intermediate Lake during a 3-year period (2015–2017). Two barriers (each 1-m long) were used per trap in 2015 and 2016, being placed on opposite sides of a central collection cup that was about 1 m from the shoreline at time of deployment. In 2015, with two traps monitored at 4–to 18-day intervals from 19 April to 29 June, larvae were collected first during the 19 April – 7 May period and last during 16–31 May. In 2016, using the same two trap locations, …


Differences In The Critical Thermal Maximum Between Two Size Classes Of Stenonema Femoratum (Ephemeroptera: Heptageniidae), Jaiden Frantz, David Houghton Sep 2023

Differences In The Critical Thermal Maximum Between Two Size Classes Of Stenonema Femoratum (Ephemeroptera: Heptageniidae), Jaiden Frantz, David Houghton

The Great Lakes Entomologist

Temperature is an important variable affecting the behavior and survival of aquatic organisms; however, little is known about the effects of size and corresponding developmental differences on aquatic insect temperature tolerance. We tested the critical thermal maximum (CTM) of large (head capsule width mean = 3.5 mm) and small (1.9 mm) specimens of Stenonema femoratum (Say) by raising the experimental temperature by 0.1, 0.3, and 0.5ºC per minute during laboratory CTM trials. Size class and temperature increase rate combinations were randomized, and each combination was tested over four trials, for a total of 24 trials of four specimens each. Two-way …

The Great Lakes Entomologist

Abiotic factors such as temperature and depth are known to affect aquatic insect populations and are thought to be major variables that directly impact how communities are assembled and populations distributed. The purpose of this study was to examine the role of temperature and depth in structuring C. areolaris populations within a temperate freshwater quarry. Larval densities among individual sponges at different depths were determined over six months in a Pennsylvania quarry. Sponges from four depths (7.0 - 8.0 m; 8.1 - 9.0 m; 9.1 - 10.0 m and 10.1 - 12.0) were collected once per month (n = 3) …


Characterizing Insect Communities Within Thin-Soil Environments, Katherine Mcnamara Manning, Kayla I. Perry, Christie A. Bahlai Sep 2023

Characterizing Insect Communities Within Thin-Soil Environments, Katherine Mcnamara Manning, Kayla I. Perry, Christie A. Bahlai

The Great Lakes Entomologist

Natural thin-soil environments are those which have little to no soil accumulation atop hard substrates. Many of these natural thin-soil environments, such as alvars, rocky lakeshores or glades, cliffs and cliff bluffs, and barrens, are found in the Great Lakes Region of North America. Due to their ubiquity and ecosystem services they provide, characterizing insects in sensitive environments such as these is important. This study monitored insects in nine thin-soil sites, within three regions, on a 630 km latitudinal gradient in the Southeastern Great Lakes Region of North America from June - August 2019. Over 22,000 insect specimens collected were …
