Flow chart showing approximate phenology of Aprosthema tardum at 200–400 m in Var. Underlying data come from both field observations and captive breeding. The timings depicted are for an early spring, and will vary according to temperature: in cool years or following a late spring and at the higher altitude sites there may be only three rather than four partial generations. Depending on season and weather, adult females generally live for 7–10 days; eggs take from 5–14 days to hatch; larval life occupies 10–18 days; and adults emerge from summer cocoons after 7–12 days.
