Genitalia
Caterpillar
Body pink with carmine red segments dorsally, head light brown, prothoracic and anal plates orange yellow, pincula red.
Cocoon/pupa
Bionomics
The larva bores into the nuts and feeds inside the nuts of the host plant. When the nuts fall, it vacates the nut and constructs a cocoon in which it hibernates. Hibernation occurs as a late instar larva. The larval stage may last for two years. Usually only one larva is found per fruit. Pupation takes place in a cocoon spun in the soil, in litter, in rotten wood or under bark or moss.
The moths are active in the evening and later come to light.
Flight periods
The adults have been observed from May till the end of September. Most observations during June/July.
