TOXIC BROWN TAILED MOTH CATERPILLAR??

Hi there everyone. I had a quiet day. We went to do a food shop, and I did some washing etc. Later on, I decided to do some deadheading of my geraniums in the front garden. I came across this little fella on one of the leaves. it was such a striking colour. I was wondering if it was the toxic brown tailed moth caterpillar? I haven't touched it, just in case!
Thank you for following me. Take care.
