Elachista obliquella is a moth of the family Elachistidae found in Europe.
The wingspan is 8–10 millimetres (0.31–0.39 in).The head is ochreous- whitish. Antennae whitish-ringed. Forewings light grey, irrorated with blackish ;a nearly straight central whitish fascia, sometimes ochreous tinged,in male slenderer and sometimes interrupted ; tips of apical cilia whitish. Hindwings are grey. The larva is grey-greenish ; head pale brown; 2 with two brown spots. [1]
Adults are on wing from April to July and again in August in two generations per year. [2]
The larvae feed on tor-grass ( Brachypodium pinnatum ), false-brome ( Brachypodium sylvaticum ), Bromopsis erecta , Bromopsis ramosa , reed grass ( Calamagrostis species), acute sedge ( Carex acuta ), Carex hudsonii , Carex ornithopoda , Carex spicata , Carex sylvatica , cock's-foot ( Dactylis glomerata ), tufted hairgrass ( Deschampsia cespitosa ), fescue ( Festuca species), wood-barley ( Hordelymus europaeus ), crested hair-grass ( Koeleria macrantha ), melic ( Melica species) milletgrass { Milium species) and broad-leaved meadow-grass ( Poa chaixii ). They mine the leaves of their host plant. The mine starts as a narrow, brown, ascending corridor and most of the frass is deposited in the basal part. Later, the larva leaves this mine and makes a new mine in another leaf. This mine is an elongated, somewhat inflated blotch which occupies nearly the entire width of the leaf. [3] They are dull grey green with a light brown head. Larvae can be found from autumn to mid-May and again in July.
