Genomic Analysis Reveals New Species And Subspecies Of Butterflies, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin Dec 2023

Genomic Analysis Reveals New Species And Subspecies Of Butterflies, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Large-scale genomic sequencing of butterfly taxa reveals new findings that are presented here. While we focus on detecting species by comparative genomics and define subspecies as groups of populations genetically differentiated from each other but not as strongly as species (that is, subspecies as species in the making), we report other adjustments to butterfly classification. As a result, 4 subgenera, 11 species, and 6 subspecies are proposed as new. New subgenera are: Rapis Grishin, subgen. n. (type species Papilio rapae Linnaeus, 1758, genus Pieris Schrank, 1801) in Pieridae Swainson, 1820 and Callitera Grishin, subgen. n. (type species Eurygona? pulcherrima …


Reassessment Of Amblyscirtes Hegon (Hesperiidae) As A Complex Of Four Distinct Species Revealed By Genomic Analysis, Harry Pavulaan, Ricky Patterson, Nick V. Grishin Dec 2023

Reassessment Of Amblyscirtes Hegon (Hesperiidae) As A Complex Of Four Distinct Species Revealed By Genomic Analysis, Harry Pavulaan, Ricky Patterson, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

After the discovery of a unique phenotype in the southern United States with a different ventral ground color than nominotypical Amblyscirtes hegon (Scudder, 1863), which occurs in the northeastern United States, genomic analysis revealed that A. hegon is a species complex. Phenotypic, genitalic, and genomic differences of the complex are presented here. Four species are identified: A. hegon; A. nemoris (W. H. Edwards, 1864), stat. rest.; A. matheri Patterson, Pavulaan & Grishin, sp. n. (TL: USA, Mississippi, Warren County); and A. gelidus Grishin, Patterson & Pavulaan, sp. n. (TL: USA, Michigan, Van Buren County).

Species Richness Of Moths In Parks Surrounded By Varying Levels Of ​Urbanization Around Nashville, Tennessee, Maxwell Stone, Allie Bennett Nov 2023

Species Richness Of Moths In Parks Surrounded By Varying Levels Of ​Urbanization Around Nashville, Tennessee, Maxwell Stone, Allie Bennett

Science University Research Symposium (SURS)

Moths can act as indicators of environmental wellness due to their pollution sensitivity and the complexity of biodiversity required to support their life cycles. Urbanization can impact the occurrence of moths in protected green spaces. Higher moth species richness was hypothesized to occur in parks surrounded by more rural areas. Three metropolitan parks were chosen in the Nashville area: downtown, within a suburban neighborhood, and in a rural area. Tree canopy cover and degree of impervious surfaces were assessed for each park and surrounding area using iTreeCanopy. Moths were attracted to a white sheet using a mercury vapor bulb, UV …


Butterfly Classification And Species Discovery Using Genomics, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin Oct 2023

Butterfly Classification And Species Discovery Using Genomics, Jing Zhang, Qian Cong, Jinhui Shen, Leina Song, Nick V. Grishin

The Taxonomic Report of the International Lepidoptera Survey

Genomic sequencing of worldwide butterfly fauna followed by phylogenetic analysis of protein-coding genes informs butterfly classification throughout the taxonomic hierarchy, from families to species. As a rule, we attribute the same taxonomic rank to more prominent clades of comparable divergence (that is, at the same level in the tree). For species delimitation, we use criteria based on relative genetic differentiation and the extent of gene exchange between populations. We analyze the current taxonomic classification of butterflies in the light of genomic phylogenies and encounter clades that correspond to yet unnamed taxa. As a result, 11 tribes, 33 subtribes, 2 genera, …


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.


New Province Records Of Southern Ontario Caddisflies (Trichoptera), David Houghton, David Etnier Sep 2023

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.


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 …


The Community Ecology Of Ants On The Cumberland Plateau And A Taxonomic Redescription Of The Genus Stenamma Westwood, 1839 (Hymenoptera: Formicidae: Myrmicinae) In A Southeastern Treatment, Zachary Brown Aug 2023

The Community Ecology Of Ants On The Cumberland Plateau And A Taxonomic Redescription Of The Genus Stenamma Westwood, 1839 (Hymenoptera: Formicidae: Myrmicinae) In A Southeastern Treatment, Zachary Brown

Theses and Dissertations

Grassland communities represent major biodiversity hotspots across the United States. Among these grassland types is the short-leaf pine savanna, a major historical habitat along the Cumberland Plateau. The Cumberland Plateau’s grasslands are under threat due to land use changes such as urbanization and land conversion to pasture and hardwood forests. This study seeks to better understand the community ecology of ants on the Cumberland Plateau using powerlines as a comparison to degraded and historic habitats. Ants have a preference between open sites and forested sites, a separation of 44.5% on a DCA. The Simpson diversity places the short-leaf pine savanna …

Arthropod Diversity In Phytotelmata Of Calathea Capitata (Zingiberales; Marantaceae) Host Plants From Peru, Divya Dendi, Timo Förster, Caroline S. Chaboo

Department of Entomology: Faculty Publications

Cryptic habitats are often overlooked in biodiversity surveys. Phytotelmata, or plant pools, are one type of cryptic habitat that supports diverse fauna in a miniature ecosystem. This study surveys the arthropod community of two types of phytotelmata, bracts and leaf rolls, on a single species, Calathea capitata (Ruiz and Pav.) Lindl. (Zingiberales: Marantaceae), from one Amazon site in Peru. Specimens were collected from eight bracts and eight leaf rolls. A total of 55 arthropods (36 adults, 19 juveniles) were found in both phytotelmata types. In the bract samples were found: spiders (Araneae: Corinnidae), beetles (Coleoptera: Carabidae, Erotylidae, Staphylindae), flies (Diptera: …
