Lacunicambarus diogenes

(Girard, 1852)

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 constructs and inhabits burrows in wet, muddy terrestrial rather than living in permanent surface water. Its burrowing activities create refugia used by numerous other species, including documented use by eastern cicada killer (Sphecius speciosus) as habitat. The species ranges across the Atlantic Coastal Plain and Piedmont ecoregion from New Jersey to Georgia, with disjunct in Louisiana.

Identification

A primary burrowing crayfish distinguished from surface-dwelling by its lifestyle and association with burrow systems in muddy substrates. Specific diagnostic morphological features are not documented in available sources.

Habitat

Wet, muddy areas including roadside ditches, floodplains, and other where surface water is intermittently available; constructs and inhabits burrows in muddy substrates rather than living in permanent aquatic habitats.

Distribution

Atlantic Coastal Plain and parts of the Piedmont ecoregion from New Jersey, Pennsylvania, Delaware, Maryland, Virginia, North Carolina, South Carolina, and Georgia; disjunct reported in Louisiana.

Behavior

Primary burrowing crayfish that spends most of its life in self-constructed burrows; constructs and maintains burrow systems used as from desiccation and .

Ecological Role

Allogenic engineer; burrowing activity creates refugia used by numerous other . Documented example: eastern cicada killer (Sphecius speciosus) have been observed using unoccupied devil crayfish burrows as , with wasps provisioning with cicadas for their larvae.
