Hymenoclea palmii
Burrowbush Borer Moth
A clearwing moth in the family Sesiidae, notable for its wasp-mimicking appearance. The species is associated with burrobrush (Hymenoclea monogyra), a toxic desert shrub. Adults are active during the summer monsoon season in the southwestern United States and Mexico. The common name reflects its larval association with the host plant's stems or roots.
