Thanks for submitting this observation! Based on the broader form and larger size, this appears to be an Ellychnia (technically now Photinus, but the database doesn’t reflect that), and the expected species based on distribution would be Ellychnia alexanderi Fender, 1969.
Some of the characteristics of Ellychnia alexanderi include the following:
– length 7.5-10.5 mm, width 3.5-5 mm
-roseate markings on the pronotum (head shield) that extend from front to back
-pubescence is black and the body does not have a “dusty” appearance
-the dark, convex central part of the pronotum (head shield) is usually finely punctured (having tiny holes) instead of being granulate (grainy/bumpy/sandy appearance)
I have changed the observation genus and species to Ellychnia alexanderi, but the observation status will remain unverified because we would probably need to examine a specimen to confidently ID this firefly.
Thanks Richard!
I am so happy to have feedback on this specimen. I have observed a few fireflies this season and have been noticing small differences between them. Thank you for the identification tips, it will be very useful for the future.
