Systena collaris
Systena collaris is a species of flea beetle in the family Chrysomelidae, first described by Crotch in 1873. The genus Systena contains multiple species of small leaf beetles, several of which are associated with sunflower and other Asteraceae hosts. The specific epithet 'collaris' refers to a collar-like marking or structure. As a member of the flea beetle group, this species likely possesses the enlarged hind femora characteristic of the tribe Alticini, enabling jumping behavior.
