Small Yellow Underwing Panemeria tenebrata
Wingspan 19-22 mm.
A day-flying species which prefers sunny weather, this diminutive species frequents meadows, grassy downland and other open areas.
It is widely distributed, though local, over much of mainland Britain as far as southern Scotland.
On the wing in May and June, it visits various flowers in grassy meadows.
The larvae feed on the flowers and seeds of mouse-ear (Cerastium spp.), especially common mouse-ear (C. holosteoides).
