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]
