Cicindelidia
Prairie Tiger Beetles, Limestone Tiger Beetles, Miami Tiger Beetle (for C. floridana), Highlands Tiger Beetle (for C. highlandensis), Scabrous Tiger Beetle (for C. scabrosa)
Cicindelidia is a genus of small to medium-sized tiger beetles primarily distributed in North America, with greatest diversity in the southern and western United States. The genus includes several notable species groups, most prominently the abdominalis species-group containing four sand-dwelling species (C. abdominalis, C. floridana, C. highlandensis, C. scabrosa) with red venters. Many species exhibit specialized habitat associations, including thermal springs (C. haemorrhagica), limestone outcrops (C. politula), pine rocklands (C. floridana), and sand scrub habitats (C. scabrosa, C. highlandensis). Several species are of conservation concern due to restricted ranges and habitat loss.

Wetsalts Tiger Beetle
Cicindelidia haemorrhagica is a tiger beetle species notable for its ability to inhabit extreme thermal environments. In Yellowstone National Park, it is exclusively associated with hot springs ranging from pH 2.7 to 9.0 and temperatures from 29.1 to 75.0°C, where it functions as the apex invertebrate predator. The species exhibits remarkable thermal tolerance, with adults observed on substrates exceeding 50°C and showing minimal behavioral thermoregulation compared to populations in milder habitats. Outside Yellowstone, it occurs in wet salt lakes, ponds, rivers, and tidal flats across the western United States.
Limnocoris moapensis
moapa warm springs naucorid, Warm Springs Naucorid
Limnocoris moapensis is a rare species of creeping water bug in the family Naucoridae. It is endemic to warm spring habitats in the Moapa Valley of Nevada, USA. The species is known from very few observations and is considered vulnerable due to its restricted range and dependence on thermal spring ecosystems. It belongs to the subfamily Limnocorinae, a group specialized for life in aquatic environments.
Paracoenia
shore flies
Paracoenia is a genus of shore flies (Diptera: Ephydridae) found in aquatic and semi-aquatic habitats. Species within this genus are associated with thermal springs, saline or alkaline lakes, and pond margins. Larvae develop in moist substrates at water edges, while adults and larvae feed on microorganisms including filamentous blue-green algae. The genus serves as an intermediate host for parasitic water mites and has been studied as an indicator of ecosystem stability in thermal environments.
