- Abstract
Previous uncertainty concerning the number of larval stages in a strepsipteran ( Elenchus tenuicornis) was resolved by transmission and scanning electron microscope observations. The first larval instar (triungulinid) is free-living: after entering the host (a delphacid) it undergoes a normal ecdysis. The resulting second instar larva undergoes two further apolyses without ecdysis. In the male, the cuticle of the fourth instar larva tans to form the puparium, while the female becomes sexually mature without a further moult after extrusion of the cephalothorax through the host cuticle. The discarded exuviae of the triungulinid remain in the host abdomen; subsequent larval staging is made possible by the retention of the exuviae ensheathing the larva as each apolysis is accomplished.
