The wetsalts tiger beetle, Cicindelidia hemorrhagica (LeConte) (Coleoptera: Cicindelidae), is found in the western USA, including the active geothermal springs in Yellowstone National Park (YNP). Here, we characterize behavioral, ecophysiological, and morphological traits of adult C. hemorrhagica living on hot springs in YNP compared to adults living in a non-hot spring environment in Idaho. Individuals in YNP behaviorally warmed and cooled themselves at surprisingly different frequencies than those in Idaho, with YNP individuals infrequently cooling themselves even though surface temperatures were greater because of geothermal activity and consequent bottom-up heating of individuals compared to the saline-flat habitat in Idaho. After a series of lethal thermal maxima and internal body temperature experiments, our results suggest that an explanation for the differential behavior is that the adult in YNP has evolved increased heat reflectance on the ventral portion of its abdomen. This increased heat reflectance seems to be caused by a physical feature as part of the exoskeleton\u2019s ventral abdominal plate, which likely protects the beetle by serving as a heat-resistant shield. The extreme conditions in YNP seem to have selected C. hemorrhagica to be among the most thermophilic insects known.<\/jats:p>","DOI":"10.1093\/aesa\/saaf011","type":"journal-article","created":{"date-parts":[[2025,3,4]],"date-time":"2025-03-04T22:01:12Z","timestamp":1741125672000},"page":"237-247","source":"Crossref","is-referenced-by-count":1,"title":["Hot springs, cool beetles: extraordinary adaptations of a predaceous insect in Yellowstone National Park"],"prefix":"10.1093","volume":"118","author":[{"given":"Kelly A","family":"Willemssens","sequence":"first","affiliation":[{"name":"School of Natural Resources, University of Nebraska , Lincoln, NE ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"John L","family":"Bowley","sequence":"additional","affiliation":[{"name":"Department of Land Resources and Environmental Sciences, Montana State University , Bozeman, MT ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Braymond","family":"Adams","sequence":"additional","affiliation":[{"name":"Department of Plant Pathology, Entomology, and Microbiology, Iowa State University , Ames, IA ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Monica","family":"Rohwer","sequence":"additional","affiliation":[{"name":"School of Natural Resources, University of Nebraska , Lincoln, NE ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miles J","family":"Maxcer","sequence":"additional","affiliation":[{"name":"Department of Land Resources and Environmental Sciences, Montana State University , Bozeman, MT ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chelsea M","family":"Heveran","sequence":"additional","affiliation":[{"name":"Department of Mechanical and Industrial Engineering, Montana State University , Bozeman, MT ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5273-3738","authenticated-orcid":false,"given":"David K","family":"Weaver","sequence":"additional","affiliation":[{"name":"Department of Land Resources and Environmental Sciences, Montana State University , Bozeman, MT ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Tierney R","family":"Brosius","sequence":"additional","affiliation":[{"name":"Department of Biology, Augustana College , Rock Island, IL ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Erik","family":"Oberg","sequence":"additional","affiliation":[{"name":"Yellowstone National Park , WY ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Leon G","family":"Higley","sequence":"additional","affiliation":[{"name":"School of Natural Resources, University of Nebraska , Lincoln, NE ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8922-1680","authenticated-orcid":false,"given":"Robert K D","family":"Peterson","sequence":"additional","affiliation":[{"name":"Department of Land Resources and Environmental Sciences, Montana State University , Bozeman, MT ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2025,2,28]]},"reference":[{"key":"2025052202413132500_CIT0001","doi-asserted-by":"publisher","first-page":"e16827","DOI":"10.7717\/peerj.16827","article-title":"Heavy metal movement through insect food chains in pristine thermal springs of Yellowstone National Park","volume":"12","author":"Adams","year":"2024","journal-title":"PeerJ"},{"key":"2025052202413132500_CIT0002","doi-asserted-by":"publisher","first-page":"532","DOI":"10.1111\/php.12889","article-title":"Elytra absorb ultraviolet radiation but transmit infrared radiation in Neotropical Canthon Species (Coleoptera, Scarabaeinae)","volume":"94","author":"Alves","year":"2018","journal-title":"Photochem.
