multiple forms in different moult cycles. Four bands with MW of 140000 Da, 50000 Da, 35000 Da and 25000 Da are discerable in the freshmoult stage. In the postmoult cuticle, the band with MW of 25000 Da is not detectable. Only two bands with MW 140000 Da and 50000 Da are visible in the intermoult cuticle. These two bands are faint in the premoult stage
