Dung beetles are beetles that feed on faeces (dung). Beetles in some species of dung beetles can bury dung 250 times their own mass in one night. Many dung beetles, known as rollers, roll dung into round balls, which are used as a food source or breeding chambers.
Hover flies are true flies, but they look like small bees or wasps. They are the helicopters of the insect world, often seen hovering in the air, darting a short distance, and then hovering again. These beneficial insects are valuable tools in the fight against aphids, thrips, scale insects and caterpillars.
