Bittacus occidentis  Walker, 1853

Diagnosis:  This is a pale brown species that lacks the apical crossvein.  The male epiandrial lobes are narrow and extend slightly beyond apex of the basistyles with small, dark denticles along the mesal margin of the apical half.  The male cerci are short.


Distribution – Geographical:  This species is found over much of the eastern half of the U.S.A., but is seldom common in ary of the areas it inhabits.


Distribution – Temporal:  Although this species is occasionally collected in June, most records are from late summer – August and September.


Ecology:  Although sometimes collected in the eastern U.S., this species is most frequently collected in the grasslands of the Great Plains.  This is one of the few species in North America that is attracted to lights.


Biology:  The immature stages and development of this species were recorded by Setty (1940).


Notes: The name occidentis probably refers to the fact that this species is from the Western Hemisphere.
