Preliminary study on the wing scales of moth, Creatonotus transiens Walker, 1855 (Lepidoptera: Erebidae)

Abstract

Dimensions of different types of scales on the wings of the moth Creatonotos transiens Walker were analyzed using micrometry. A total of 65 morphologically distinct types of scales were investigated, including 35 from dorsal side and 30 from ventral portion. Dorsal side scales have a length range of 82.7 to 141.3? and width range of 55.1 to 78.8?. The length of scale on the ventral region ranged from 82.7 to 133.9? and width 63 to78.8?. On comparison with ventral side of wing most of the dorsal side scale forms are long narrow and dentate.
