Florida intertidal firefly (fiddler crab firefly)


This interesting firefly is only found at the intertidal zone of coastal salt marshes in the the following counties of Florida:  Levy, Citrus, Hernando, Pasco, Pinellas, Hillsborough, Manatee, Sarasota, Volusia, Brevard, Indian River, and St. Lucie.  The larval stage (left photo) is luminescent as well as the adult (right photo).  As the common name indicates, the larva of this species is found where fiddler crabs often burrow.  This rare, but beautiful beetle is now threatened due to habitat destruction.
