Cereal capuchin
Rhyzopertha dominica
The cereal capuchin is the main pest of cereals in the USA and is also on the rise here. Just as fatal as the grain moth The neck shield of the 3 mm long, black-brown beetle is hooded over the head. The strong constriction behind the neck shield and the dotted stripes on the wing covers are striking. 300-500 eggs are laid on cereal grains. The larvae develop and pupate in the grain. At normal temperature approx. 2 generations per year. If the grain is stored too warm, development takes approx. 5 weeks, corresponding to several generations per year.
