Limited genetic parallels underlie convergent evolution of quantitative pattern variation in mimetic butterflies.

Nevertheless, the prevailing opinion is that populations of adult damselflies and dragonflies do not exhibit such senescence. Here, we challenge this contention by fitting a range of demographic models to ...
