Genus Bittacus
Explanation of Names
Author of genus is Latreille, 1805.
Appears to be from Greek Bittakos/Byttakos (βιττακος/βυττακος), early spelling of Greek Psittakos, meaning parrot. (Arnott, Birds in the Ancient World from A to Z, Routledge, 2007--via Googlebooks). Bittacus is also listed by Forror as Greek, meaning parrot (1). Named for the long "beak", resembling (vaguely) that of a parrot?
Numbers
By far the largest genus of the family, with 7 spp. north of Mexico (over 120 worldwide: 51 in Africa, 37 in Asia, 25 in Central & South America, 2 in Europe, and 1 in Australia)(World Checklist):
Bittacus chlorostigma MacLachlan, 1881
Bittacus occidentis Walker, 1853
Bittacus pilicornis Westwood, 1846
Bittacus punctiger Westwood, 1846
Bittacus stigmaterus Say, 1823
Bittacus strigosus Hagen, 1861

Identification
Bittacus are typical members of family, wings unmarked, rest with wings folded. B. chlorostigma has green patch (stigma) on front margin of wing, found in southern California.
Range
Worldwide; in North America, mostly the eastern half of the continent, with just one Pacific species (B. chlorostigma: CA, OR), one species restricted to KS, TX, and NM (B. texanus), and five widely distributed over the eastern states (B. occidentis west to AZ; B. strigosus northwest to MT; the rest reach areas west of the Mississippi to NE--TX), with three ranging into Canada (two along the se. border and one west to MB). (Webb et al., 1975; Cheung et al., 2006; World Checklist)
Habitat
Woodlands.
Season
May-October (various species, North Carolina)
Food
Predatory on smaller insects, esp. dipterans.
