Castalius rosimon (Fabricius) commonly  available in northwestern India has been reared on the leaves of its natural host plant, Zizipus oenoplia Mill. (Rhamnaceae) in Himachal Pradesh. Detailed examination of the chaetotaxy of first instar caterpillar has been attempted and the position of various setae and lenticles has been discussed. The crochets have been recorded to be uniserial and uniordeal.
