The forewing colour is either light ochreous brown or dark fuscous, both occuring in a single population.

Foodplant and Larval Feeding Signs

Foodplant unknown in Britain.

In Europe found in the rootstocks of Filipendula ulmaria (meadowsweet) and, although unconfirmed, Spiraea spp. (brideworts) are mentioned.


Principally a moth of Fens and damp localities but has also been found in gardens, limestone hills and dry fields.

Finding the Moth

Larva: in Europe believed to feed in the rootstock of meadowsweet.

Adult: flies at night and comes regularly to light traps.

On 22 July 1849 reported as being found amongst Hippuris vulgaris (Mare's-tail) by Allen Hill in a note by J W Douglas in the Trans. Ent. Soc. London 1847-52. In 1866 reported as being found on the 'heads of large cuckoo weed'.

Similar Species

Similar to some other Monochroa species, the two colour forms adding to potential confusion. In its dark form, size should help separate it from the smaller M. conspersella, M. hornigi and M. elongella. The abdomen on M. lutulentella has segments one to four ochreous yellow above, the other segments being fuscous. This feature should assist in separating it from the three previously mentioned species as well as worn specimens of the marginally smaller and narrower-winged M. lucidella. Dissection may be necessary.
