The dried pupae of this Hepialidae are windblown into clumps. Every time it rains there is another emergence. The dry weather seems to have favoured rhis moth!
Abantiades atripalpis is commonly called the Rain Moth. I guess if it rains too much before they pupate (at the top of their burrow): the larvae get drowned in their burrows.
I always thought that many moths and butterflies emerged from the cocoon or chrysalis when the environment was likely to be favorable for them to continue their life cycle, eg feed on nectar, lay eggs which develop into caterpillars to feed on plants.
