Sitochroa dasconalis is a North American crambid moth known as the Pearly Indigo Borer. First described by Francis Walker in 1859, it occurs from the northeastern United States west to Texas. The species is notable for its larval specialization on Baptisia tinctoria, a leguminous plant commonly called wild indigo. Adults are active during spring and early summer.
Uresiphita
Uresiphita is a genus of crambid moths comprising approximately six recognized species distributed across North America, New Zealand, Europe, and the Middle East. The genus is notable for larval sequestration of quinolizidine alkaloids from leguminous host plants, a chemical defense mechanism against predators. Several species have expanded their ranges through association with introduced host plants.
