Nematinus luteus

Sawfly Nematinus luteus

Description

Nematinus luteus is a species of sawfly in the family Tenthredinidae. The adult Nematinus luteus is a small sawfly, usually yellowish to orange in color, with distinct black markings on its body. The wings are transparent, typical of many sawflies. The larvae are more commonly seen as adults and are caterpillar-like in appearance, greenish with darker longitudinal stripes, which help them blend into the foliage of alder trees. They have a lot of white spots on the body. Nematinus luteus is primarily associated with alder trees, particularly in riparian (riverbank) environments where these trees are common. Sometimes can feed olso on Corylus avellana. This species is found in parts of Europe where alder trees grow. The larvae feed on the leaves of the alder, often skeletonizing them by consuming the leaf tissue between the veins. This feeding can cause significant damage to the foliage if the population is high. After completing their feeding, the larvae drop to the ground where they pupate, often in the soil or leaf litter. While the feeding activity of Nematinus luteus larvae can defoliate alder trees, healthy trees typically recover well. However, repeated infestations or additional stressors can weaken the trees over time. This is species not ussualy not very common and only localy can outbreak.
