Destructive flour beetle
…but in Denmark, at least in comparison with other pests. Destructive flour beetle beetles were first found in Denmark in 1943, but they have since appeared more often. The Destructive flour beetle most likely came to Denmark from the tropics in Africa in connection with trade of goods between the two places. Anyhow it has also occurred in other countries that have traded with this part of the world. In Danish, the Destructive flour beetle is named…
