Firefly to the north, lightning bug to the south
By whatever name, a June delight

Neither flies nor true bugs
Beetles, really
Bioluminescent beetles
Latin, Lampyridae from the Greek, lampein
To shine
And they do
Shine
A light
made possible by the mixing Of oxygen and luciferin  

Flashing is their love language
Each species with its own rhythm
Beating out Come hither lover
Come hither
