(1)Identification
A key to nearly all species north of Mexico as of 1935 was written by Brennan (1935).
These views should make it possible to identify every Deer Fly in our area:
view showing dorsal head, thorax, abdomen; also wing pattern
lateral view showing, antennae, thorax, leg colour
face view showing frontal callus (black oval between eyes), frontoclypeus (yellow shiny triangle below eyes), palps (below frontoclypeus); also legs
frontal/lateral view of face. Only 1 view of face, either this view or that shown in 3 is required
clear view of wing, also shows clear view of abdomen
