We examined habitat use and foraging activity of the endangered Hawaiian hoary bat (Lasiurus cinereus semotus), as well as nocturnal aerial insect abundance at Kaloko-Honōkohau National Historical Park located in the coastal region of Kailua-Kona, Hawai‘i Island. The study area covers approximately 486 ha of marine waters and terrestrial coastal plains. Nocturnal aerial insect collection occurred in January and April (2 or 3 nights each) and in July and November (1 or 2 nights each) in 2014. Insects were collected at three stations (KAHO1, KAHO3, KAHO4) between 1 and 10 m above sea level. Nocturnal aerial insects were collected using a 22 W UV light placed above a funnel and bucket trap (Model #2851M, Bioquip Products...

Conclusions: Valleys are the only areas capable of sustaining sufficient habitat for the butterfly species, Weidemeyer's Admiral. Consequently, all other areas (i.e. plains, uplands, benches, escarpments, plateaus) were deemed unsuitable. Additionally, areas devoid of shrub cover did not meet the habitat requirements of this specialized species. Thresholds/Learnings: Synopsis: Two variables were selected to model potential habitat for the butterfly species, Weidemeyer's Admiral. Topographical features derived from the Agricultural Region of Alberta Soils Inventory Database (AGRASID) and percent shrub cover derived from the Native Prairie Vegetation Baseline Inventory developed by Alberta Environment were used to...

The dataset consists of abundance information of butterfly species (61 species) collected at 25 sites in northwest Indiana in 1998 and 1999. Each site was surveyed 21 times. Auxiliary data on environmental conditions were collected to allow us to relate habitat differences among sites to differences in abundance and composition of the butterfly community.

The citizen science pilot began in April of 2023 and ends in November of 2023. Based on the response and number of specimens received the collection efforts may continue into 2024. The Lepidoptera Research Collection (LRC) will be made available to all scientists within the USGS to conduct research. States included in the pilot study (Nebraska, Kansas, Oklahoma, Texas, Georgia, and Alabama) were selected based on at least one of three factors: 1) locality relative to the migration pathway of the Monarch butterfly, 2) presence of confined animal feeding operations (CAFOs), or 3) locality relative to the Corn Belt. The Environmental Organic Chemistry (EOC) unit, located at the Kansas Water Science Center, will specifically...

Conclusions: Emigration rates are closely tied to edge structure. Low contrast edges promote edge permeability Thresholds/Learnings: Synopsis: The behavior of two butterfly species, one habitat specialist and one habitat generalist, were tracked at four prairie edges to determine the extent to which edge structure affects emigration. The specialist species responded strongly to all edges, and was particularly affected by edge density. The generalist species responded strongly only to high contrast edges. Emigration rates are closely tied to edge structure. Therefore, promoting low contrast edges in conservation planning may positively influence edge permeability and species richness in highly fragmented landscapes.
