They have a peculiar distribution, restricted to the Old World tropics of Southeast Asia to Australasia and Madagascar.
The mainly day-flying Callidulinae can be distinguished by their resting posture, which is the most butterfly-like, with the wings held closely over the back.
Resembling the butterfly family Lycaenidae, these moths can be told apart by their antennae which taper to a point or may be very subtly clubbed.
The more often night-flying Pterothysaninae and Griveaudiinae have a different adult resting posture (the latter roof-like in repose) and these were not placed within the Callidulidae until recently.
Eggs are very flat in Griveaudiinae and Callidulinae, and caterpillars of Callidulinae are green with a shiny black head and have only been reported from ferns[2] forming a leaf roll in which they live, eat and finally pupate, while the pupa of Helicomitra appears to be subterranean.
