Asclerini
false blister beetles
Asclerini is a tribe of false blister beetles within the family Oedemeridae, established by Gistel in 1848. The tribe encompasses more than 40 genera and over 200 described species. Members are soft-bodied beetles commonly associated with flowers and vegetation. Asclerini represents one of the major lineages within the Oedemeridae, a family known for containing the cantharidin-producing "false blister beetles."
