Light orange underwing

As promised, the light orange underwing  Boudinotiana notha from yesterday. 
This scarce (Nationally scarce B) moth flies from March - April in Southern England usually found in open woodland associated with Aspen.  it is similar to and can be confused with the Orange Underwing, but they can be distinguished on several characteristics, the Light Orange underwing is generally smaller, and has less verigated forwings than the Orange underwing. Also on the underside of the hindwing the dark outer band is unbroken.
Having taken all the above info into consideration I am sure this is a Light orange underwing  and a really nice find.
