Orchestes (Rhynchaenus) fagi

Beech flea weevil

Description

In spring, as the leaves start to grow, overwintered adults of Rhynchaenus fagi appear. These adults measure about 1.5-3 mm in length, and are characterized by their black bodies, red legs, and antennae. Females of this species lay their eggs close to the central vein of the leaf, on the lower side. Upon hatching, the larva first feeds on the vein, and then creates a typical mine between two lateral veins. As it nears the edge of the leaf, the larva creates a surface mine, which results in the drying up of the leaf's edge and the appearance of perforations. When the adults emerge, they move onto the leaf, feed on it, and cause additional perforations.

Symptom

Gradually from the vein to the edge of the leaf expanding mine.
