Here's some of the Tiger moth caterpillars I saw whilst poking around out on the reserve yesterday.
Wood tiger
Ruby tiger
Garden tiger
And one I've been unable to ID so far. It's not a tiger - I think it might be an instar of one of the eggars - but if anyone knows what it is I'd be grateful to hear from you. It was found on the reserve last week on open grass on a cliff top not far from heather.
