Photinus pyralis

Photinus pyralis, commonly known as the common eastern firefly or lightning bug, is a species of beetle famous for its bioluminescent glow. Found in North America, especially in the summer months, these insects produce light through a chemical reaction in their abdomen, used primarily for attracting mates and deterring predators. The male fireflies typically fly and flash to signal females, who respond with their own flashes. Their enchanting glow and synchronized flashing create beautiful displays, and their presence indicates healthy, moist habitats. Despite their name, fireflies aren’t flies but beetles, and their glowing ability makes them a symbol of summer nights.
