Silver Y - Autographa gamma

Bradley & Fletcher No.: 2441

The Silver Y is probably the UK’s most common immigrant moth. It flies by day and night, with the swift-flying adults frequently observed nectaring at flowers by day and just before dusk. It is also readily disturbed from vegetation by day. In some years it can be especially numerous, particularly near the south coast. The massive immigration of 1996 was on an unprecedented scale and was measured in billions! The larvae feed on a wide range of low-growing plants, including bedstraws, Clovers, Common Nettle, Garden Pea and Cabbage. It can occur almost anywhere, from coastal habitats to inland sites, and can be frequent in gardens.
