Scarlet Tiger Moth

Probably recently emerged, resting on the branch of a horsetail in the sunshine on Wednesday morning, a beautiful moth.

‘Scarlet’ because the hindwings are a stunning colour, peeking through here, but seen most clearly when they fly.

This caterpillar was crossing the towpath in mid-April, perhaps having arisen from its winter dormancy ready to feed-up, pupate and, a month later, transform into an adult moth. Not unexpected in the Reserve as its food plants include Hemp Agrimony and Comfrey, which are growing in the Orchard, besides nettles and bramble. Typically adorned with a colourful warning pattern (aposematic colouration) and toxic hairs to deter predators.

Keep an eye out over the next few weeks as the adult moths are generally only around through May and into early July.
