Apethymus apicalis

Sawfly Apethymus apicalis

Description

Apethymus apicalis is a sawfly species found across Europe, primarily feeding on plants from the Rosaceae family, particularly Rosa multiflora, Rosa rubiginosa, and Rosa rugosa. It is a monophagous species, meaning it specializes in feeding on roses. The larvae feed freely on leaves, consuming leaf tissue and causing skeletonization. Eggs overwinter on the host plant, and larvae emerge in spring, feeding on leaves before pupating.

Repeated defoliation can weaken rose plants, reducing their overall vitality and affecting their ornamental value. While Apethymus apicalis does not typically cause severe damage, heavy infestations can lead to significant leaf loss and stress on the plant. This species is widely distributed across Europe and can be found in various habitats where its host plants grow.

Symptom

Larvae feed on leaf surfaces, causing irregular skeletonization. Affected leaves may develop translucent patches or small holes. Severe feeding can lead to leaf curling, deformation, or complete defoliation.
