The raspberry beetle is also called the common raspberry. This is a representative of the raspberry beetle family of the same name, which, contrary to the name, eats not only raspberries.
The bugs are small, 3-4 mm. They are often gray, black and rarely reddish, completely covered with gray or red hairs. Due to their small size, they can go unnoticed for a long time.
Life cycle
Raspberry beetle.
Initially, forest raspberries become the source of infection. The bugs start up where the landings are excessively thickened. In the absence of raspberries, the bugs eat bird cherry, blueberries and cloudberries.
In spring, at a temperature of +12 degrees and above, pests are activated. They eat greens to restore their strength. They actively mate and lay eggs in buds. When the ovaries appear, the caterpillars are also selected.
Within a month and a half, they eat berries, actively working with their jaws. After harvesting, the caterpillars choose a place for themselves in the raspberry roots and overwinter there. They pupate at the beginning of the warm season.
