It is a first for Britain, a male Fall Webworm Moth Hyphantria cunea distinguished by antennae, all white abdomen with no dorsal spots, no spots on the hindwing, and spines on the tibiae, something the genus Spilosoma doesn't have.
It has been recorded in North America from Canada to Mexico, introduced accidently in Europe in the 1940's and spreading Eastwards into Central Asia, also in Japan in 1945.
The nearest record to here is known from South-West France!
Chuffed to say the least, need to write an article now for the Entomologist record.
