Habitats. Hoverflies can be found in every biotope but not in deserts. Each species tends to prefer a certain type of habitat and is limited to a distinct range within the country. There are relatively few species with broad habitat tolerances that enable them to be distributed throughout southern Africa.

They feed on damp and decaying vegetable matter and are beneficial as recyclers of organic matter.However, they become a pest when they migrate into buildings.Millipedes are usually found in the garage, basement or lowest level although they may wander into other parts of the house.hey feed on damp and decaying vegetable matter and are beneficial as recyclers of organic matter.
