The Delicate Mythimna vitellina

(Hübner, [1808])

Wingspan 36-43 mm.

A migrant species, appearing most commonly on the south and south-west coasts of England, usually between August and October, but also sometimes earlier in the season.

The adults vary in colour from very pale yellow to almost orange.

It is considered that some of the earlier migrants during the year may breed in Britain, giving rise to autumn adults, but the larval stage is not well known due to its nocturnal and retiring nature.
