The Cuticle and Wax Secretion in Calpodes Ethlius (Lepidoptera, Hesperidae)

M. LOCKE 1

1 Department of Zoology, University of Cambridge

Larvae of Calpodes ethlius have an area of integument specialized for the secretion of long hollow filaments of wax. The epicuticle in this region has numerous cratershaped tubercles about 0.5 µ in diameter, from the rims of which the filaments are secreted. Rows of tubes 60 Å in diameter emerge round the rims of each crater. The wax is supposed to traverse these tubes nnd they have been termed ‘wax canals’. On the inside the wax canals ramify irregularly. Tubes that appear to be similar occur elsewhere in the epicuticle, where they may be concerned with normal wax secretion. The epicuticle consists of cement, a cuticulin layer 60 to 100 Å thick, and an inner dense layer of variable thickness. Microfibres are described in the endocuticle.
