Gentle Readers,
Daniel has watched the sunset the past three nights in Ohio and as soon as the sun drops below the horizon, the Lightning Bugs start flashing.  Based on the flash patterns, flash colors, and the flying habits, Daniel is certain there are numerous species present, but alas, he does not have the necessary skills to identify them to the species level.

Firefly

Because it is still light enough to see, Daniel continued to eradicate invasive prickly thistles that have overrun parts of the yard, and he found this shy Firefly flashing from the sedum.  The day before, Daniel tried unsuccessfully to capture the experience of watching hundreds of flashing Fireflies with the camera on his iPhone, but alas, much like photos of the Grand Canyon, it is not the same as being there and experiencing it.  As a side note, it is also nice to watch the bats flying in the twilight catching insects.

Larviform Female Firefly

Dear Lauren,
16 years ago we posted a similar looking image of a Firefly from Colorado that Arthur V. Evans (through Eric Eaton) identified as a pink female
Microphotus pecosensis. We believe you likely encountered the same species, and here is a BugGuide image for comparison.

Your letter to the bugman:  I’m thinking this is a male Glow Worm Beetle that is…
Zarhipis integripennis?

Firefly

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.

Male Glowworm

This is an adult male Glowworm Beetle.  Unlike Fireflies that have bioluminescent abilities, only the larval Glowworm glows.  The larval Glowworm is sometimes called a Railroad Worm.
