Head capsule width of larvae of Neozephyrus japonicus japonicus (Murray) (Lepidoptera, Lycaenidae)

Abstract

Head capsule widths of Neozephyrus japonicus japonicus larvae collected in Ibaraki Prefecture, Central Japan were measured. The butterfly passes through four larval instar stages before pupation. The mean head capsule widths of the first, second, third and fourth (final) instar larvae were 0.331, 0.585, 1.059, and 1.909 mm, respectively.
