Orange Underwing
This medium-sized moth can be confused with the Orange Underwing, but can be distinguished from that species on several characters. It is generally smaller and the forewing is less variegated than that of the Orange Underwing. On the underside of the hindwing the dark outer band is unbroken. Additionally the Orange Underwing usually flies about two weeks earlier than the Light Orange Underwing, the former being associated with birch.
A spring species usually seen flying in sunshine around the tops of Aspen. Less active in the late afternoon. Sometimes found lower down or on the ground visiting puddles.
Starts flying about two weeks later than the Orange Underwing from March to April.
Aspen (Populus tremula)
Found in open woodland where mature catkin-bearing Aspen are frequent.
