Crustacean biology and ecology

Deinocerites spanius (Dyar and Knab) is a member of a genus of mosquitoes whose larvae are found almost exclusively in the holes of certain species of crabs. The genus is a small one, limited in distribution to the shores of the Caribbean Sea, Gulf of Mexico, and adjacent regions. The larvae live in the water which fills the lower portion of the crab holes, while the adults rest in the holes above the water. Both males and females have extremely long filiform antennae and short palpi so that the sexes can scarcely be separated except by means of the genitalia. Only one species, Deinocerites cancer Theob., has heretofore been recorded from the United States. Its distribution in this country is limited to southern Florida, where the larvae are found in the holes of the large land crab.
