The urticating apparatus in the larva of the Lappet Moth, Streblote panda Hübner, 1820 (Lepidoptera: Lasiocampidae)

摘要

A morphological study of the urticating apparatus in the last larval instar of Streblote panda Hübner, 1820 (Lep- idoptera: Lasiocampidae) was undertaken using a scanning electron microscope. It is composed of two meso- and metatho- racic crevices, accompanied by urticating hairs, which open when the caterpillar is threatened. The urticating hairs taper at both ends and are mostly smooth but ringed on their distal part, which also features about 400 pores allowing the ur- ticating liquid to be released.
