Tree Crickets

Tree crickets deposit eggs in punctures in long rows in the canes of raspberries. Each puncture is distinct and more or less circular in outline, so the row of eggs appears as a series of dots, from a few to more than fifty.

The eggs are laid through the outer layer of the wood and placed diagonally across the pith. Eggs usually are laid beginning in August. Egg-laying injuries occasionally girdle and kill the cane above the injury. Eggs hatch into tiny nymphs in the early spring near the end of May. During the five nymphal stages, the crickets are a snowy-white color, but they take on a greenish color after molting to the adult stage. All stages feed on a variety of plants.

Tree crickets rarely have been reported as a serious problem in Pennsylvania, although small infestations have been noted. If egg-laying damage is noted, clip off the cane below the egg-laying scars and destroy it.
