1 thought on “Observation: Microphotus”

  1. Thank you for submitting this observation, and nice job documenting an adult female glow-worm firefly! I will confirm with colleagues who have more expertise about Arizona fireflies, but this appears to be an adult female in the genus Microphotus. I believe there are several species that might occur in this part of AZ.

    The pdf “A Guide to Fireflies of the Southwest” by Anna Walker is a great resource to learn more.
