Large Yellow Underwing.

Large Yellow Underwing.

Observation - Large Yellow Underwing.. Description: This is puzzling me, though I expect it shouldn't. At first glance I thought it was a Broad-bordered Yellow Underwing, but not with those jagged cross-lines and pale oval and light head. It's more like a Pearly Underwing but it doesn't have the crest.
