The larvae are covered with long hair of various kinds. Some of the hair is the cause of skin irritation in people. They feed primarily on […]
Bean weevils
In seeds of the various kinds of pea and bean plants different granivorous weevils live. They infest the seeds already when the plants are in the fields and are later on transported to warehouses where they can continue to do damage. The result is seen as rotten peas, beans, lentils etc. Most of these weevils […]
The rice weevil
Latin: Sitophilus oryzae. Very similar to the granary weevil, and you cannot tell the difference with the naked eye. With a little magnification however, it is possible to see that the rice weevil has four red spots on the elytrons.

Like all furniture beetles the larvae live in burrows, which they gnaw and the result is […]
The rust-red flour beetle
Latin: Tribolium castaneum (synonym: T. navale). This beetle differs from the confused flour beetle by the three external antennae joints being much thicker than the ones of said beetle. The antennae joints of the confused flour beetle are gradually thicker toward the tip. Both in terms of biology, harmfulness and extermination the rust-red flour beetle […]
The confused flour beetle
Latin: Tribolium confusum. 3-4 mm long beetles ranging in colour from light reddish brown to dark brown.
