Occurs in fields from May to August. 



Var. warringtonellus (Plate 9. fig. 5) is a local variety 

 oiperlellus, all the intermediate stages occurring. 



The larva feeds in perpendicular tubular galleries on 

 Aira flexuosa and other hard grasses. It hybernates 

 and pupates the following spring in a cocoon half sunk 

 in the earth. 



The ground-colour of the larva is dirty greyish green, 

 paler on the belly. The head and plate on the second 

 segment are light brown marked with darker; spots 

 dark brown, lighter on the sides than the back ; spi- 

 racles black. E. M. M. xviii. 129.

Common in damp meadows in July and August. 



This species can easily be distinguished from tristellus 

 by its broader and shorter fore wings, its ochreous 

 colour, and the absence of the hind line. 



The larva feeds upon Poa mnrUima and other coarse 

 grasses, inhabiting a green frass-covercd gallery, in 

 which it finally pupates, first spinning up the end. 



The larva is brown, becoming paler towards the belly ;
