I always remember how excited I was to find a Sallow kitten caterpillar feeding on Poplar leaves that I had collected for some other species. So I mistakenly thought it was the slightly larger Poplar kitten moth.
This attractive moth is a much smaller version of the larger Puss moth the caterpillars feed on sallow, aspen and poplars. There are two generations a year in the south of UK.
The Sallow Kitten makes a cocoon the same as the Puss moth when it is time to pupate this caterpillar makes a cocoon on a branch or bark by chewing bits of wood and mixing it with silk it matches tree almost exactly and hardens making it an excellent camouflaged cocoon to stay safely in through the winter.
