I've not seen them before - they're on door frames and in corners - they were little green catterpillars and they've stuck themselves in awkward places and turned into spiky little grey things.
My question is - are they going to hatch soon into moths or something, or are they butterflies waiting until next year?
I don't want to pick them off if they're going to be something nice, but they won't be hanging around for a whole year will they? How long before the very hungry catterpillar hatched? Why are they all in my house?
That's all, thank you.
