Identification

-level identification of Bombylius diegoensis requires examination of wing venation, particularly the location of the r-m (radial-medial) crossvein, which distinguishes Bombylius from the similar Systoechus. of Bombylius species generally exhibit spring activity, whereas Systoechus species tend to be active in fall. Precise identification to B. diegoensis likely requires reference to and original description.
