Allotments 4 All

Hi folks - wonder if anyone can help please.

Was at a BBQ at the weekend and left my chair for a few moments - when I went back there was a hairy caterpillar on my chair - have been googling all morning and can't find out what it is.    Its features were -

fawn bristly hairs all over
tufts of yellow short hairs (like spots) running down the top of its back
black tufts that looked like antennae
a black tuft like a little sticky-up tail close to its rear end

(Maybe it is my imagination, but I have had a nasty spotty irritation on my arm since then  :o)

Any clues as to what it was that I saw?

hi decrepit
did your caterpillar look like this?

Hi there!  Gosh that was a quick reply  ;D

Pretty close, but he wasn't so dark - definitely light fawn hair all over (quite long but not tufted) with yellow tufts and his black antennae and 'tail'.

(My Dad called all hairy caterpillars 'hairy oobits').
