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

摘要

A morphological study of the urticating apparatus in the last larval instar of Streblote panda Hubner, 1820 (Lepidoptera: 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 urticating liquid to be released.
