Identification
4 views should make it possible to identify every Deer Fly found in North America. The following images by the Strickland's are superb and I encourage everyone to try and obtain similar views for any Deer Fly she/he photographs:
1 - view showing dorsal head, thorax, abdomen; also wing pattern
2 - lateral view showing, antennae, thorax, leg colour
3.1 - face view showing frontal callus (black oval between eyes), frontoclypeus (yellow shiny triangle below eyes), palps (below frontoclypeus); also legs
3.2 - frontal/lateral view of face. Only 1 view of face, either this view or that shown in 3 is required
4 - clear view of wing, also shows clear view of abdomen
