Ellychnia is a genus of fireflies. First defined by Émile Blanchard in 1845, the genus contains 24 species, [1] which are widespread in the United States. [2] Adults are black, with rose-colored marks on the pronotum; [3] sexual dimorphism is unknown. [4] These beetles are active during the day, and have no light-producing organs as adults; [5] instead, they attract mates using chemical signals. [6] The larvae of Ellychnia fireflies live in rotting logs. [4]
