I found these caterpillars on a bush in my garden this morning and I’ve been struggling to find an ID all day and it’s now started to bug me (pun intended!).
Can anyone help?
The longest one is about 1”/25mm long and they seem to be living in the web tent/cocoon you can see behind them. They all took shelter inside the web when we had a brief rain shower! I guess that there are about 50+ in total.
