Species account |
 |
A small (c.1-2mm) barkfly. Rare in England. Females can have long wings (macropterous) or tiny wings (micropterous). Males have short wings (brachypterous). |
 |
Female (macropterous)
As with all Lachesilla species the forewings are completely hairless. The wing has no characteristic features (see also L. quercus). The abdomen does not have brown rings (cf. L. pedicularia) |
 |
Female (micropterous)
Very small size helps to distinguish this species from other apterous (no wings) and micropterous (tiny wings) species. |
 |
Female
The subgenital plate has a simple curved shape without lobes on the apex (see also L. pedicularia).
