Physonota
tortoise beetles, hispines
Physonota is a genus of tortoise beetles and hispines in the family Chrysomelidae, containing more than 40 described species. Species in this genus are distributed across North America, with records from the United States and Canada. The larvae possess distinctive defensive structures: shields made of feces and exuviae held over the body using urogomphi. Host plant associations have been documented for some species, though many remain poorly studied.
