Thank you for submitting this observation, Emily! These fireflies were most likely the southwest spring firefly (Bicellonycha wickershamorum) based on the early evening display time, the flash pattern description, and the location being a known site for this species.
I am going to leave the observation status as “unverified” because it’s hard to know for sure without a photo of the firefly in hand. The sky island firefly (Photuris falli) has also been recorded in Cochise County, so that is also a possibility, though less likely.
