Web worms

I'd not noticed before but the hedges where we walk suddenly seem filled with these webs, and when you look closer they are full of caterpillars.  Apparently they are ermine moth caterpillars and they looked amazing this morning.

I was keen to blip them today as we have had rain all day and I don't know how they will have fared by tomorrow.  They may have all disappeared so I will have missed my chance.
