Insects are one of the most diverse groups of animals in the world and include beetles, butterflies and bees. They are found across a range of different habitats including rainforests, deserts, mountain tops and even the Antarctic. Insects also live in cities and other urban areas.
All insects belong to a larger groups of animals called arthropods. This means they have a segmented body covered in an exoskeleton and pairs of jointed limbs.
There are over a million known arthropod species. Arthropods include insects, arachnids, myriapods and crustaceans.
Case study: Native bees
Australia is home to over 1500 species of native social and solitary bees as well as a number of introduced species. They have two antennae and two pairs of wings extending from the thorax. Bees have a proboscis for extracting nectar from flowers.
Native bees nest in places such as hollow trunks, tree branches, rock crevices and in underground burrows. They are also known to build smallhives in wall cavities and the brick work of houses.
Some types of native social bees can be kept in built hives.
