Moths – The Delicate (Mythimna vitellina)

The Delicate

Key facts

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.

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.


Forewing angular, pale yellow to orange-brown, or orange-red. Cross-lines fine, dark brown, inner and central lines jagged, often with a dark dot at the trailing end of the wing. The adults vary in colour from very pale yellow to almost orange.
