December 2011. A caterpillar eating castor oil, Binh Thuan, Vietnam for identification.
It was identified as a lymantriid,Olene mendosa. Hübner. See, www.mothsofborneo.com/part-5/orgyiini/orgyiini_3_1.php.
It looks like some Dasychira spp. and Euproctis spp. among the common lymantriids of Southeast Asia. O. mendosa is highly polyphagous and castor is one of its host plants.
