Phyllaphis fagi

Woolly beech aphid

Description

The woolly beech aphids overwinter as eggs in buds or bark. The eggs hatch close to bud break. The first individuals are very descriptively called ancestress. The mothers are giving birth to young ones, which are forming colonies at the lower site of the leaves. Infected leaves curl downwards from the edges and fall off if heavily infected. The lower side of the leaf is sticky due to honeydew and gets dirty (settled dirt) as season ends. Brown necrotic spots appear on young leaves. It can be very common in some years.

Symptom

There are white coatings on the underside of the leaves.
