Lampyris atra G. Olivier, 1790 Lucidota atra, the black firefly or woodland lucy,[3] is a diurnal species of firefly — a member of the Lampyridae family of beetles (order Coleoptera).

Their range extends west to Kansas, Nebraska, Oklahoma and Texas[3] and south to Mexico.

[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.

[13] Lucidota atra express a characteristic set of odorant receptor genes in their antennae.

[9] The flightless larvae live in moist environments, especially decaying wood, and prey on invertebrates with soft bodies, such as snails and slugs.
