Schwegler Insect Block Woodcrete

Most species of Hymenoptera that live in hollows and recesses do not make the excavations themselves.Instead they occupy existing holes, made by certain types of beetles, in which they construct their brood cells. Because they regulate the numbers of insect pests, Hymenoptera are of major ecological and agricultural (and also economic) importance.

Much of our countryside has been cleared and cultivated and consequently there are not enough natural nesting places. Everyone should make an effort to provide nesting aids for insects.
