The Brick Agrochola circellaris
Wingspan 33-38 mm.
One of several similar, orange-coloured species which emerge during the autumn period, it is distributed widely over much of Britain and is fairly common.
It frequents mainly woodland and parkland, and is on the wing from August to October.
The larvae feed on the flowers and leaves of wych elm (Ulmus glabra) or poplar (Populus) when young, later feeding on the leaves.
