found on the net curtain in my bedroom

swiftly went down the hoover so only got this one pic, looks pretty mean!

Spoiler

it was 2-3 inches long, what ever comes out of it must have be huge

Looks very similar to the first Lymantriidae moth caterpillar in cosimos link. It got hoovered because as said above some of them sting and i didnt fancy getting stung!
