Your letter to the bugman:  I’m thinking this is a male Glow Worm Beetle that is…
Zarhipis integripennis?
How you want your letter signed:  Bomberojohn79


Dear Bomberojohn79,
The Western Glowworm males pictured on BugGuide have orange legs.  We actually believe this is a Firefly,
Pterotus obscuripennis, based on this BugGuide image, and according to BugGuide:  “comes to lights in spring/early summer.”

Thank you so much for setting me straight.
