Comparative approach:
Lac insects show a striking sexual difference in their development. Females are neosclerotic and never pupate, passing directly from the crawler (larval) stage to the sessile adult, so their life cycle has only three stages. Males, however, undergo a complete developmental sequence: they hatch from the egg, pass through mobile and settled larval instars, then enter a non-feeding pupal stage inside a test, before finally emerging as a short-lived winged adult that dies soon after mating.
Because the question specifically asks about the male life cycle, all four stages, egg, larva, pupa and adult, are present.
