Delta esuriens
Okinawa Mud Wasp
Delta esuriens is a potter wasp species distributed across tropical Asia. Females construct mud nests with pot-shaped entrance holes, provisioning cells with lepidopteran caterpillars as food for developing larvae. The species is distinguished from the similar Delta pyriforme by a yellow band on the metasomal petiole. Development from egg to adult emergence spans approximately one month, with males emerging earlier than females due to shorter development times.
