Nematus oligospilus, commonly known as the willow sawfly, is a species of sawfly in the family Tenthredinidae. Native to central and northern Europe and Asia, it was first recorded in South America in the 1980s and New Zealand in 1997, and has also been introduced to Australia, South Africa and Lesotho.
Leaves show a characteristic curling, similar to damage caused by viruses. Heavily infested plants have shortened internodes leading to resetting or a "bunchy top" appearance. A heavy, black, sooty mold may develop on an infested plant's leaves and stems as a result of the mealybug's heavy honey-dew secretions.
The flowers are yellow catkins, 3–8 cm (1 + 1 ⁄ 4 – 3 + 1 ⁄ 4 in) long, produced in the spring with the leaves. The reddish-yellow fruit matures in late spring or early summer, and the individual capsules are 4–6 millimetres (3 ⁄ 16 – 1 ⁄ 4 in) long. [5] [6] The peachleaf willow grows very quickly, but is short-lived.
These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones . [ 1 ]
