Horse Fly - Tabanus limbatinevris - female

Horse Fly - Tabanus limbatinevris - Female
Gettysburg, Adams County, Pennsylvania, USA
August 5, 2005
Size: 18mm
A specimen from my collection. Looks similar to species Hybomitra epistates based on other images in the guide. Can anyone confirm? Thanks!

Tabanus limbatinevris
I would agree that although the first posterior cell is not close and petiolate, I would call it limbatinevris. A small percentage of limbatinevris do have the cell not closed, although not commonly. The narrow frons is also indicative, as indicated by Tony.


Moved from Flies.

Not a Hybomitra
Have been re-thinking some tabanid ID's. I believe this is a female Tabanus limbatinevris based on the narrow frons and small pale dorsal abdominal triangles. However, the narrowly open 1st posterior cell of the wing is suggestive of T. sulcifrons. The Pennsylvania locality would seem to rule out T. abdominalis. Part of a difficult (to ID) complex of species.
