A very common species from May to August.

 distinguished from other species by the narrow dull 

 white subcostal and central streaks. 



Var. alfacarellus. In this variety the fore wings 

 are rather broader, the second line is less angulated, 

 and the ground-colour is white. 



The larva feeds amongst roots of grass [Aira flexuosa) 

 in silken galleries. The ground-colour is dingy brown ; 

 head brown marked with darker ; tubercles dark olive- 

 brown ; anterior legs black ; spiracles black ; plates on 

 the second and anal segments polished. The tubercles 

 give the skin a rough and uneven appearance. 



The larva hybcrnates, and pupates in spring in a 

 slight cocoon among the roots of grass.
