 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.Biology of most subfamilies and species is poorly known.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 forming a leaf roll in which they live, eat and finally pupate, while the pupa of "Helicomitra" appears to be subterranean.
