Marbled Minor - Oligia strigilis


Wingspan 22-25 mm. One of a complex of three species, which can only be reliably separated by dissection of the genitalia. The other two species are Tawny Marbled Minor (O. latruncula) and Rufous Minor (O. versicolor). The identification of this group is further complicated by the relative frequency of melanic specimens.

Where a photograph is surrounded by a red box it means the subject is likely to be this species but has not been definitively identified as such.

Identification difficulty

Grassland, fens, woodland, heathland, scrub and gardens.

When to see it

Flying from May to July.

Life History

The larvae feed in the roots and stems of a number of grasses.

UK Status

Common and widespread, occurring throughout most of Britain. In a recent survey to determine the status of all macro moths in Britain this species was classified as common.

VC55 Status

As an aggregate group the Minor species are common in Leicestershire and Rutland, but there are not many confirmed records. L&R Moth Group status = A (G) (common and resident, but genitalia examination needed for secure identification)
