Diagram of the proposed lifecycle of Epicephala moths on Breynia oblongifolia over three successive generations (F1–3). The black cycle denotes the life history for the majority of individuals, in which moths go through two generations per year with the winter months spent as eggs or small larvae in overwintering female flowers. Egg diapause may also occur during the summer months in periods with insufficient rainfall to initiate fruiting. The grey cycle denotes the alternative strategy taken by 12% of individuals in the autumn crops, in which pre-pupal larvae emerge from fruits and enter diapause for 38–48 weeks, re-joining the general population 1–2 generations later. The number of generations skipped depends on the duration of the diapause. Here, a pre-pupal diapause of 52 weeks is depicted
