Range

edit

Lucidota atra are found in eastern North America. Their range extends west to Kansas, Nebraska, Oklahoma and Texas[3] and south to Mexico.[4]

Description

edit

Adult body length is 9 to 12 mm (0.35 to 0.47 in).[7] This firefly has segmented, conspicuous, black antennae that are serrate, with males having larger antennae.[8]: 84 [9] The pronotum extends over the head and is usually red and yellow with a medial black stripe or patch,[7] but may be dark overall in some individuals.[10] The compound eyes are smaller than those of nocturnal species like Photinus pyralis.[11] The elytra are black or brown-black[7] and have granulated texture.[10] The light organ is greatly reduced and difficult to discern in the adult.[8]: 30 

Behavior

edit

This is a firefly that flies actively in daylight. Males fly low, about 1 to 6 ft (0.3 to 1.8 m) from the ground, through forests in midday, seeking females, which are often perched on low vegetation. Most are seen in the late morning to early afternoon.[9] Male Lucidota atra can identify female mating partners by sensing the female's pheromones with their antennae.[12] Lucidota atra express a characteristic set of odorant receptor genes in their antennae.[11] Both males and females are able to fly.[9]

Life cycle

edit

Adults

edit

Adults emerge in early to midsummer. In eastern Canada, larvae eclose beginning in late May, and adult numbers peak in late June to mid-July.[13] In the southern Appalachians, numbers peak in mid- to late June.[9]

Eggs, larvae, and pupae

edit

Once the adults mate, the female lays eggs that hatch in about 2 to 3 weeks.[9] The flightless larvae live in moist environments, especially decaying wood, and prey on invertebrates with soft bodies, such as snails and slugs.[3] The larvae or pupae are inactive in the winter, becoming adults in early to midsummer.[14]

Habitat

edit

L. atra are found primarily in open forest or shady open areas.[9]

Light production

edit

Adults have no working lanterns, although they often have pale terminal abdominal segments. Larvae are bioluminescent.[9]
