The Old-World butterfly-moth family consisting of three subfamilies, eight genera are distributed throughout Southeast Asia to Australasia and Madagascar and exhibit both day and night flying behaviour. 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 Lycaenidae butterfly. 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 and described as roof-like in repose. The caterpillars of Callidulinae are green with a shiny black head and have only been reported feeding on ferns, forming a leaf roll in which they live, eat and finally pupate.
