Lachesilla pedicularia is a species of Psocoptera from the family Lachesillidae.

[3] Some features distinguishing this from other species of Lachesilla are the abdomen having brown stripes, the forewing being hairless, wing vein R1 meeting the wing edge almost at a right angle, and several other wing veins being marked with brown.

The subgenital plate of females forms a simple curved shape, while the hypandrium of males has simple (not forked) appendages.

[3] This species occurs on the trunks and (to a lesser extent) branches of a range of trees, including beech, birch, broom, oak, pine, spruce, and yew.

[1] It is also known from haystacks, straw bales, nests of robins, barns, houses, and stored grain.
