Silver Y

Scientific Name: 
Autographa gamma

The Silver Y is a medium-sized moth that can be seen on warm days throughout the year, although it is most common during the late summer. The caterpillars feed on a wide variety of plants, including Stinging Nettles, clover and cabbages. At times, this migrant may be a very common visitor, especially in flowery grasslands, sand dunes and gardens. It can often be seen flying during the daytime, feeding on nectar from plants, such as buddleia and lavender, but also flies at night. It breeds here but the early stages cannot survive our winter.

How to identify: 
When at rest, the Silver Y holds its wings back along its body in a tent-like shape. The wings are patterned with dark grey, silver and brown, with the characteristic silver y-shaped mark on the forewings.
Where to find it: 
Widespread.
How people can help: 

Moths such as the Silver Y are common visitors to gardens and can be a joy to watch. To attract moths and butterflies into your garden, plant nectar-rich borders and shrubs for them to feed on, and leave patches of nettles and docks for the caterpillars.
