Dinumma
Dinumma is a genus of moths in the family Erebidae, established by Francis Walker in 1858. The genus contains approximately 11 described species distributed across South and Southeast Asia, with one species introduced to North America. Adults exhibit characteristic wing venation and palp structure typical of the subfamily Calpinae. Larvae of at least one species demonstrate unusual aquatic locomotion behavior.
Dinumma deponens
curved-ribbon
Dinumma deponens is a moth in the family Erebidae (formerly Noctuidae) first described by Francis Walker in 1858. Native to Asia, it has been introduced to North America with established populations in the southeastern United States. The species is notable for its larvae's ability to escape drowning through specialized undulatory locomotion on water surfaces. Larvae feed on Albizia species, particularly Albizia julibrissin.
Microgaster
Microgaster is a genus of braconid wasps in the subfamily Microgastrinae containing more than 100 described species with worldwide distribution. Species within this genus are koinobiont endoparasitoids of Lepidoptera larvae, with some exhibiting highly specialized behaviors. The genus includes the first documented microgastrine to dive underwater to parasitize hosts (Microgaster godzilla) and species with distinctive morphological adaptations such as modified tarsal claws. Host associations vary widely, with records from multiple lepidopteran families including Crambidae, Noctuidae, Depressariidae, and Hesperiidae.
