Heterelmis
riffle beetles
Heterelmis is a genus of aquatic beetles in the family Elmidae, commonly known as riffle beetles. The genus includes several described species, with Heterelmis comalensis being particularly notable as an endangered species endemic to spring systems in Texas. Members of this genus are fully aquatic, inhabiting oxygen-rich flowing water environments where they feed on microbial biofilms. Some species have reduced or non-functional wings, limiting their dispersal ability and making them vulnerable to habitat degradation.

Lacunicambarus diogenes
devil crayfish, devil crawfish
Lacunicambarus diogenes, commonly known as the devil crayfish or devil crawfish, is a primary burrowing crayfish native to eastern North America. This species constructs and inhabits burrows in wet, muddy terrestrial habitats rather than living in permanent surface water. Its burrowing activities create refugia used by numerous other species, including documented use by eastern cicada killer wasps (Sphecius speciosus) as brooding habitat. The species ranges across the Atlantic Coastal Plain and Piedmont ecoregion from New Jersey to Georgia, with disjunct populations in Louisiana.
