Biology & Ecology

The site of oviposition is highly variable both between host plants and geographical locations, but is generally in the vicinity of the emerging inflorescence. Completion of embryonic development takes 3-4 days. Upon emerging the larvae move into the inflorescence where they commence feeding on the skin of the developing fruit. The larvae feed in sheltered positions on hands still covered by bracts. As bracts lift to expose fruit, larvae move down to the next protected hand. Development proceeds for 11-19 days, through five larval instars. The development period for both sexes terminates in a quiescent prepupal period of around 2 days, and the pupal period is 8-10 days.
