Oslar's oakworm moth
Anisota oslari is a saturniid moth native to the southwestern United States and Mexico. Adults are day-flying and active during summer months, with a single annual generation. The larvae are specialized feeders on oak species (Quercus), with documented hosts including sandpaper oak (Q. pungens), Mexican blue oak (Q. oblongifolia), and shrub live oak (Q. turbinella). Larvae exhibit gregarious behavior when young, becoming solitary as they mature. The species overwinters as pupae in shallow underground chambers.
