Marbled Minor Oligia strigilis


Family Noctuidae » Subfamily Xyleninae » Oligia strigilis (Linnaeus, 1758) 73.173 (BF2337)
Wingspan 22-25 mm. This moth is very variable. It is only representative of the species as there are two other species, the Tawny Marbled Minor (Oligiala truncula) and Rufous Minor (Oligia versicolor), which are very much the same and can only be reliably separated by genitalia dissection. The larva feeds on the roots and stems of various grasses. The adult flies May to July, and is readily attracted to light. They are found in a wide range of grassy habitats, including woodland rides and gardens. Out of the three Oligia species this is the most commonest and widespread.
