Port Eynon caterpillar

The caterpillar we collected on 1st Jan has grown substantially and is 26mm long after moulting a few times. It's clear now that it is a Square-spot Rustic, so our tentative Mythimna id was clearly wrong and a reminder that attempts at identifying young larvae are likely to have a high degree error.

    Or could it be Six-striped Rustic? Not sure it's possible to reliably tell the two apart as larvae.

    Nice photo!

    Cheers

    Thanks George, I'd overlooked that, though the probability of it being Square-spot Rustic is very much higher.
