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

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 Caddisflies (Trichoptera) Of Finch Creek, Antrim County, Michigan (Usa), David Houghton, Robert Haack

The Great Lakes Entomologist

The caddisfly assemblages of Finch Creek, a small woodland stream in northern Lower Michigan, was sampled along its entire continuum during May, June, July, and September 2021–2022 using ultraviolet blacklight traps. A total of 98 species representing 15 families and 49 genera were collected, including two species [Lepidostoma prominens (Banks) and L. sommermanae (Ross)] not previously reported from Michigan, and several others either not previously found in the Lower Peninsula or not reported from the state for >70 years. A non-metric multidimensional scaling ordination determined distinct species assemblages corresponding to the spring, summer, and fall months. Shredders dominated the …

The Caddisflies (Trichoptera) Of Drummond Island, Michigan, With An Assessment Of Lake Assemblage Biomass, David Houghton, Robert Haack

The Great Lakes Entomologist

The adult caddisfly assemblages of Drummond Island, a Michigan island in Lake Huron near the Canadian border, were sampled in 2021–2022 from 3 sites on Lake Huron, 8 inland lakes, 2 vernal pools, and 1 stream. Adult caddisflies from each site were sampled in spring, summer, and autumn using ultraviolet blacklight traps. A total of 89 species representing 37 genera and 12 families was collected, including several not seen in Michigan for 50–70 years and the first confirmation of the rare species Beothukus complicatus (Banks) (Phryganeidae) from the state. A non-metric multidimensional scaling ordination determined distinct species assemblages between lakes, …

New Province Records Of Southern Ontario Caddisflies (Trichoptera), David Houghton, David Etnier

The Great Lakes Entomologist

Thirty-two caddisfly species are reported from Ontario for the first time, including 24 in the family Hydroptilidae, three in the Hydropsychidae, and one each in the Leptoceridae, Limnephilidae, Molannidae, and Polycentropodidae. The known caddisfly richness of the province increases from 309 to 341 species, including a doubling of the known hydroptilid fauna. Many more species undoubtedly remain to be discovered in this large and relatively undisturbed province.

Temporal Changes In Temperature May Suggest Microhabitat Shifts In Larval Spongillafly Climacia Areolaris Hagen (Neuroptera: Sisyridae) Abundance And Density In A Temperate Freshwater Lake, John R. Wallace, M. Eric Benbow, Cindy Willman-Kinsey

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

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 …

Prevalence of Gregarine Protozoa Infection in Zygoptera Sourced from Varying Collection Sites in Keith County, Nebraska

B.G Kircher II, A. Kadubandi, and S.L. Gardner S. H.W. Manter Laboratory of Parasitology, University of Nebraska-Lincoln and Cedar Point Biological Station, University of Nebraska-Lincoln

Damselflies are ubiquitous flying insects of the order Odonata with thousands of species found around the world. The parasites associated with damselfly species are equally as ubiquitous, with the most common being gregarine protozoa and water mites, though other parasitic organisms such as trematodes are also found in these animals. Gaining an understanding of the relationships among hosts and …

Agricultural Pesticide Regulatory Environment For Pollinator Protection Across Geographical Regions, Ngoc T. Phan, Edwin G. Rajotte, Guy Smagghe, Zong-Xin Ren, David J. Biddinger, Neelendra K. Joshi

Entomology and Plant Pathology Faculty Publications and Presentations

The alarming decline of pollinator populations has raised significant concerns worldwide and prompted the need for effective pesticide risk assessment within the Integrated Pest and Pollinator Management (IPPM) framework. This paper examines the diverse approaches to pollinator protection within the pesticide regulatory environments of the United States (US), the European Union (EU), and selected Asian countries. The US adopts a reactive approach, regulating pesticides only after evidence of harm emerges, while the EU embraces a proactive stance under the precautionary principle. The EU has implemented stringent regulations, including neonicotinoid bans, and conducts coordinated research on pesticide impacts. In contrast, some …

Architecture, Construction, Retention, And Repair Of Faecal Shields In Three Tribes Of Tortoise Beetles (Coleoptera, Chrysomelidae, Cassidinae: Cassidini, Mesomphaliini, Spilophorini), Caroline Simmrita Chaboo, Sally Adam, Kenji Nishida, Luke Schletzbaum

University of Nebraska State Museum: Entomology Papers

Animal constructions are the outcomes of complex evolutionary, behavioural, and ecological forces. A brief review of diverse animal builders, the materials used, and the functions they provide their builders is provided to develop approaches to studying faecal-based constructions and faecal-carrying in leaf beetles (Coleoptera: Chrysomelidae). Field studies, rearing, dissections, photography, and films document shields constructed by larvae in two species in two tribes of the subfamily Cassidinae, Calyptocephala attenuata (Spaeth, 1919) (Spilophorini), and Cassida sphaerula Boheman, 1853 (Cassidini). Natural history notes on an undetermined Cassidini species and Stolas cucullata (Boheman, 1862) (Tribe Mesomphaliini) outline the life cycle of tortoise beetles …

Editorial. In: Chaboo Cs, Schmitt M (Eds) Research On Chrysomelidae 9, Caroline S. Chaboo, Michael Schmitt

Department of Entomology: Faculty Publications

This is volume 9 in the series ‘Research on Chrysomelidae (RoC-9)’. This started from RoC-1 in 2008, named as a series to reflect the dream of Pierre Jolivet for a long tradition into the future. This dream was built on previous special volumes of Chrysomelidae research that emerged largely through Jolivet’s efforts since 1988 (‘Biology of Chrysomelidae’) and from various international symposia. For example, ‘Special Topics in Leaf Beetle Biology’, edited by David Furth, emerged from the International Congress of Entomology held in Iguassu, Brazil in 2000.

Chalcochares Hirsutifemur (Banks) (Hymenoptera: Pompilidae: Pompilinae), A Probable Obligate Parasitoid Of Aptostichus Simon (Araneae: Mygalomorphae: Euctenizidae) In California, Frank E. Kurczewski, Alice J. Abela, Akira Shimizu

Insecta Mundi

Size equivalence, seasonal synchronicity, geospatial sympatry, habitat specificity, and host-search­ing behavior implicate the spider wasp Chalcochares hirsutifemur (Banks) (Hymenoptera: Pompilidae: Pompilinae) as an obligate parasitoid on species of the wafer-lid spider genus Aptostichus Simon (Araneae: Mygalomorphae: Euctenizidae) on coastal sandy back dunes in San Luis Obispo and Santa Barbara coun­ties, CA. This is substantiated by 2010–2022 macrophotographs, videos, and field observations. Such host evidence supports recent unpublished phylogenomic studies that place Chalcochares as a sister genus of the spider wasp tribe Aporini, in which all species are known obligate parasitoids on trapdoor spiders and related Mygalomorphae. Chalcochares hirsutifemur and C. …
