Speciation of a winter geometrid moth

Winter harshness separates reproductive season of I. punctigera at highlands and high latitudes in Japan. The separated seasonal populations are reproductively isolated even if they are in sympatric.

Copulation of I. punctigera. Wingless female is a feature of winter geometrid moths.

Early winter population and late winter population are completely separated in time in the regions with cool winter. On the other hand, the reproductive season is not separated in the regions with warm winter.

Evolutionary ecology of periodical cicada

How is the evolution of 13- and 17-year cicada [wikipedia]? We revealed the divergence age of Broods, which are groups of cohorts emerging in the same year.
