The Small Yellow Underwing (Panemeria tenebrata) is a species of moth in the Noctuidae family.


This small moth is easy to identify by it's dark colour on it's forewings, and yellow hindwings. This species flies by day, and can only really be mistaken for Pyrausta despicata, which lacks the yellow hindwing, but also flies by day. The hindwing has a thick black border.

Distribution & StatusEdit

This species is local in Britain, inhabiting grasslands in May and June. More common in southern Britain, this species is easiest to see in the afternoon. This species may be more common than it appears, as it is small and probably overlooked.


The larva feed on Common and Field Mouse-ear, and can be seen from June till July, after which it pupates.
