Chrysalis

Dave Cheetham (March)



This butterfly chrysalis was hanging from a tree branch down by Llyn Mymbyr. I have no idea what kind of butterfly will emerge from it, only that it is a butterfly. If it were a moth cocoon it would be on the ground or in loose vegetation lower down and wrapped in a protective silk case.


The caterpillar will have wrapped itself up in this hard protective coating to sit out the winter, whilst inside it develops (or metamorphoses) into a butterfly. This chrysalis is very well camouflaged, concealing it from predators and must have been very well attached to last the strong winds of winter in such an exposed position.

In spring it will appear as a butterfly and go on to lay eggs which will develop in to caterpillars and hopefully go on to become chrysalids like this one, completing the butterfly lifecycle.
