Cycnia
Cycnia is a genus of tiger moths in the family Erebidae, erected by Jacob Hübner in 1818. The genus contains several North American species, including the well-studied dogbane tiger moth (Cycnia tenera), which is known for its sophisticated anti-bat acoustic defenses. Species in this genus are typically associated with dogbane and milkweed plants, sequestering cardiac glycosides for chemical protection.
