Here's a general question, no photo this time.
I notice when I am looking at gray bristly flies that resemble houseflies, sometimes they have tiny spines along the leading edge of the wing.
I found a reference that said Anthomyiid flies have spinules, and Dung Flies (Scathophagidae) usually don't.
Are the presence of these spines along the wing edge used to help ID other families? Do flies in Muscidae or Tachinidae or Calliphorida have spinules, always/sometimes/never?
Thanks for any guidance you can give about this.
