Photinus indictus, or silent firefly,[2] is a species of firefly in the beetle family Lampyridae. It is a diurnal firefly, active during the day rather than at night, with no lanterns. It is found in eastern North America.[3][4][5]

Description

P. indictus is a small to medium-sized beetle, with adults approximately 6–10 mm (0.2–0.4 in) long. The head shield, or pronotum, is pale yellow with a thick, black, rectangular central mark with red or pink on both sides. The wing covers, or elytra, are dark with wide, well-defined, light-colored margins. Unlike fireflies that produce light as adults, P. indictus has no lanterns on its abdomen. The female is often slightly larger than the male.[2]

Etymology

Photinus is from the Greek word for shining or bright.[6] The specific epithet, "indictus", is Latin meaning "not said" or "unspoken", referring to the fact that this species does not flash as an adult.[7]

Life Cycle

Beetles such as P. indictus go through four life stages: egg, larva, pupa, and adult. Photinus fireflies spend the majority of their lives as larvae, which are bioluminescent and likely live below the soil surface, eating snails, worms, and other soft-bodied invertebrates.[1][2]

Behavior

Adult P. indictus fireflies are believed to attract mates through airborne pheromones.[8]

Habitat

They can be found in meadows, pastures, and fields.[2]

Range

P. indictus is found in eastern North America, most commonly in the Great Lakes region of the United States and Canada.[1]
