Wingspan 23 to 26 mm. An attractive reddish brown species.

Identification difficulty
Recording advice

In view of the rarity of this moth in our area, please provide a photograph and retain the specimen in case it is required by the County Recorder.


It inhabits grassland and chalk quarries where the food plant Wild Marjoram occurs. We are unsure at present whether it may be attracted to Marjoram in gardens. 

When to see it

It flies in the second half of July and early August at dusk and later comes to light. On warm nights it has been recorded well away from its normal habitats.

Life History

The larvae feed on Wild Marjoram, and spin the leaves of the terminal shoots together when fully grown.

UK Status

Very local, with most records coming from the county of Kent, Recent light trap records seem to suggest that this species is perhaps less scarce than once thought.

VC55 Status

Rare in Leicestershire and Rutland. The Thurlaston specimen taken on 27th July 2020 is the first record for VC55.
