Brachypanorpa jeffersoni  (Byers, 1976)


Diagnosis:  This species may be differentiated from the only other eastern U.S. species of Brachypanorpa , B. carolinensis, by its smaller average size and paler coloration; and by the possession of ocellar setae.  Males have a ridge-like projection along the ventral edge of the dististylar basal lobe.  Females have wings that extend only to the second abdominal segment (Byers, 1976), while wings of female B. carolinensis extend to the tip of the abdomen.


Distribution – Geographical:  Southwestern Virginia, adjacent North Carolina and eastern Tennessee at 1280 to 1400 m elevation.


Distribution – Temporal:  9 to 29 June (Byers, 1997).


Ecology:  As indicated by Byers (1997), individuals rest on a variety of low, herbaceous plants in the montane forest, but the species of plant may vary with the elevation.  The habitat always appears to include old, rotting logs in an advanced state of decay.  Adults appear in pockets of what is a far larger, generalized habitat.


Biology:  Byers (1997) has found that species of Brachypanorpa lay eggs in clusters in rotting wood and soil.  Larvae are scarabaeiform, lack prologs, are blind, and live in the soil.  Larval food is still unknown.


Notes:  The name Brachypanorpa refers to the short wings of the females, and jeffersoni refers to Mt. Jefferson where the type series of this species was collected, and Thomas Jefferson, the third president of the United States..
