Head capsule width of larvae of Curetis acuta paracura de Nicéville (Lepidoptera, Lycaenidae) in Kanto, Central Japan

Abstract

Head capsule widths of Curetis acuta paracura larvae collected in Tokyo (Hachioji) and Ibaraki (Tsukuba), Central Japan, were measured. The butterfly passes through four larval instar stages before pupation. The mean head capsule width of the first, second, third and fourth (final) instar larvae were 0.346, 0.574, 0.952, and 1.834 mm, respectively.
