Moths – Silver Y (Autographa gamma)

Silver Y

A well-known migrant species, this moth can turn up in thousands under the right conditions, especially at coastal migration watch-points. It can occur anywhere in Britain, and in autumn, the breeding population from spring migrants is swelled by further migration.

The adults can be found from spring through till late autumn, and can be seen by day as well as at night, when they regularly visit light.
