What distinguishes
bellula from the rest of the "bellula species group"?

Simpler eye markings, less ornamented thorax, long second antenna segment (about as long as third), face with hairs instead of scales, and range. There is one Eastern species, three Southwestern, and one more broadly distributed in the West. See reference on species group info page.

Probably Orthonevra bellula
