Nematus leucotrochus is a species of sawfly in the family Tenthredinidae, known as the pale-spotted gooseberry sawfly. Widespread throughout central and northern Europe, this insect is best known as a pest of gooseberries. The larvae feed on the foliage of the plant, defoliating it. Unlike Nematus ribesii , the common gooseberry sawfly, the species has a single brood. Adults appear in early May and larvae in May and June. ^[2]

Control measures include hand-picking larvae in the early stages of an attack, or spraying with a recommended insecticide. ^[3]
