Abstract: Three new species of Psychocampa Grote and Robinson, 1867 are described from Central and South America: one from Costa Rica and Panama: P. ursa n. sp.; and two from Peru: P. antonkozlovi n. sp. and P. yuliyakovalevae n. sp.. The female of the somewhat rarely reported P. kohlli Herbin, 2012 is figured and described, along with its genitalia, for the first time. Four new country records are also provided for P. kohlli.

The Cicinninae Schaus, 1912 is the most diverse subfamily of diagnostic structures of Psychocampa genitalia always allow mimallonids, and contains three tribes. The cicinnines are for unambiguous placement of species into this genus, and among the largest Mimallonidae, and are found throughout the more broadly within Psychocampini when considering the New World, from Canada to Argentina (St Laurent & Kawahara, minor, albeit consistent, differences between Psychocampa 2019). The taxonomic histories of two of the cicinnine genera, and its sister genus Biterolfa Schaus, 1928. The present Cicinnus Blanchard, 1852 and Psychocampa Grote and article describes three new species of Psychocampa based on Robinson, 1867, have been particularly confusing, and it was not morphological examination, further expanding our knowledge until the molecular phylogeny of St Laurent et al.

Additionally, I describe and figure be sufficiently phylogenetically distinct to warrant placement the female of P. kohlli Herbin, 2012 for the first time. in separate tribes: Cicinnini Schaus, 1912 and Psychocampini St Laurent and Kawahara, 2018, respectively.

This is especially true for skippers (Hesperiidae), one of the most species-rich and poorly studied butterfly families. Methods: To infer a robust phylogenomic hypothesis for Hesperiidae, we sequenced nearly 400 loci using Anchored Hybrid Enrichment and sampled all tribes and more than 120 genera of skippers.

  • Influence of Habitat and Bat Activity on Moth Community Composition and Seasonal Phenology Across Habitat Types
    INFLUENCE OF HABITAT AND BAT ACTIVITY ON MOTH COMMUNITY COMPOSITION AND SEASONAL PHENOLOGY ACROSS HABITAT TYPES BY MATTHEW SAFFORD THESIS Submitted in partial fulfillment of the requirements for the degree of Master of Science in Entomology in the Graduate College of the University of Illinois at Urbana-Champaign, 2018 Urbana, Illinois Advisor: Assistant Professor Alexandra Harmon-Threatt, Chair and Director of Research ABSTRACT Understanding the factors that influence moth diversity and abundance is important for monitoring moth biodiversity and developing conservation strategies. Studies of moth habitat use have primarily focused on access to host plants used by specific moth species. How vegetation structure influences moth communities within and between habitats and mediates the activity of insectivorous bats is understudied. Previous research into the impact of bat activity on moths has primarily focused on interactions in a single habitat type or a single moth species of interest, leaving a large knowledge gap on how habitat structure and bat activity influence the composition of moth communities across habitat types. I conducted monthly surveys at sites in two habitat types, restoration prairie and forest. Moths were collected using black light bucket traps and identified to species. Bat echolocation calls were recorded using ultrasonic detectors and classified into phonic groups to understand how moth community responds to the presence of these predators. Plant diversity and habitat structure variables, including tree diameter at breast height, ground cover, and vegetation height were measured during summer surveys to document how differences in habitat structure between and within habitats influences moth diversity. I found that moth communities vary significantly between habitat types.

  • Impacts of Native and Non-Native Plants on Urban Insect Communities: Are Native Plants Better Than Non-Natives?
    Impacts of Native and Non-native plants on Urban Insect Communities: Are Native Plants Better than Non-natives? by Carl Scott Clem A thesis submitted to the Graduate Faculty of Auburn University in partial fulfillment of the requirements for the Degree of Master of Science Auburn, Alabama December 12, 2015 Key Words: native plants, non-native plants, caterpillars, natural enemies, associational interactions, congeneric plants Copyright 2015 by Carl Scott Clem Approved by David Held, Chair, Associate Professor: Department of Entomology and Plant Pathology Charles Ray, Research Fellow: Department of Entomology and Plant Pathology Debbie Folkerts, Assistant Professor: Department of Biological Sciences Robert Boyd, Professor: Department of Biological Sciences Abstract With continued suburban expansion in the southeastern United States, it is increasingly important to understand urbanization and its impacts on sustainability and natural ecosystems. Expansion of suburbia is often coupled with replacement of native plants by alien ornamental plants such as crepe myrtle, Bradford pear, and Japanese maple. Two projects were conducted for this thesis. The purpose of the first project (Chapter 2) was to conduct an analysis of existing larval Lepidoptera and Symphyta hostplant records in the southeastern United States, comparing their species richness on common native and alien woody plants. We found that, in most cases, native plants support more species of eruciform larvae compared to aliens. Alien congener plant species (those in the same genus as native species) supported more species of larvae than alien, non-congeners. Most of the larvae that feed on alien plants are generalist species. However, most of the specialist species feeding on alien plants use congeners of native plants, providing evidence of a spillover, or false spillover, effect.

  • Caterpillars on the Foliage of Conifers in the Northeastern United States 1 Life Cycles and Food Plants
    INTRODUCTION INTRODUCTION Coniferous forests are important features of the North American landscape. In the Northeast, balsam fir, spruces, or even pines may dominate in the more northern forests. Southward, conifers still may be prevalent, although the pines become increasingly important. In dry, sandy areas, such as Cape Cod of Massachusetts and the Pine Barrens of New Jersey, hard pines abound in forests composed of relatively small trees. Conifers are classic symbols of survival in harsh environments. Forests of conifers provide not only beautiful scenery, but also livelihood for people. Coniferous trees are a major source of lumber for the building industry. Their wood can be processed to make paper, packing material, wood chips, fence posts, and other products. Certain conifers are cultivated for landscape plants and, of course, Christmas trees. Trees of coniferous forests also supply shelter or food for many species of vertebrates, invertebrates, and even plants. Insects that call these forests home far outnumber other animals and plants. Because coniferous forests tend to be dominated by one to a few species of trees, they are especially susceptible to injury during outbreaks of insects such as the spruce budworm, Choristoneura fumiferana, the fall hemlock looper, Lambdina fiscellaria fiscellaria, or the pitch pine looper, Lambdina pellucidaria. Trees that are defoliated by insects suffer reduced growth and sometimes even death. Trees stressed by defoliation, drought, or mechanical injury, are generally more susceptible to attack by wood-boring beetles, diseases, and other organisms. These secondary pests also may kill trees. Stress or tree death can have a negative economic impact upon forest industries.

  • Pest Risk Assessment of the Importation Into the United States of Unproc- Essed Eucalyptus Logs and Chips from South America
    United States Department of Agriculture Pest Risk Assessment Forest Service of the Importation into Forest Products Laboratory the United States of General Technical Unprocessed Eucalyptus Report FPL−GTR−124 Logs and Chips from South America A moderate pest risk potential was assigned to eleven other Abstract organisms or groups of organisms: eucalypt weevils In this report, we assess the unmitigated pest risk potential of (Gonipterus spp.), carpenterworm (Chilecomadia valdivi- importing Eucalyptus logs and chips from South America ana) on two Eucalyptus species other than E. nitens, platy- into the United States. To do this, we estimated the likeli- podid ambrosia beetle (Megaplatypus parasulcatus), yellow hood and consequences of introducing representative insects phorancantha borer (Phoracantha recurva), subterranean and pathogens of concern. Nineteen individual pest risk termites (Coptotermes spp., Heterotermes spp.), foliar assessments were prepared, eleven dealing with insects and diseases (Aulographina eucalypti, Cryptosporiopsis eight with pathogens. The selected organisms were represen- eucalypti, Cylindrocladium spp., Phaeophleospora spp., tative examples of insects and pathogens found on the foli- Mycosphaerella spp.), eucalyptus rust (Puccinia psidii), age, on the bark, in the bark, and in the wood of Eucalyptus Cryphonectria canker (Cryphonectria cubensis), Cytospora spp. Among the insects and pathogens assessed, eight were cankers (Cytospora eucalypticola, Cytospora eucalyptina), rated a high risk potential: purple moth (Sarsina
