Loxostege ephippialis
Loxostege ephippialis is a small moth in the family Crambidae, first described by Johan Wilhelm Zetterstedt in 1839. It exhibits a Holarctic distribution, occurring across northern Europe and North America. The species is known to be a significant host for the mason wasp Euodynerus annulatus, which provisions its nests with paralyzed caterpillars of this moth. Adults are active during early summer in both European and North American populations.
