2- Eudocima apta(Adept Fruit-piercing Moth)
- Eudocima serpentifera
Eudocima is a of in the Erebidae, established by Gustaf Johan Billberg in 1820. The genus contains numerous tropical and is notable for the fruit-piercing of its , which use their specialized mouthparts to puncture fruit and feed on juices. This feeding habit has made several species significant agricultural pests. The genus has undergone taxonomic revisions, with species historically placed in various other genera.

Ecological Role
Larvae function as herbivores on various plants. act as frugivores, potentially serving as minor during fruit feeding. The fruit-piercing can facilitate entry points for fungal and other spoilage organisms in fruits.

Taxonomic History
currently placed in Eudocima have been assigned to numerous other in the past, reflecting the complex taxonomic history of the fruit-piercing moth group. The genus has been variously treated within Noctuidae, Calpinae, and now Erebidae depending on classification system employed.
Defensive Behavior
Eudocima materna exhibits a double line of defense: cryptic forewing coloration provides camouflage against tree bark, while sudden exposure of brightly colored hindwings serves as a deimatic display to startle .
