Insects have no internal bony skeleton and the adults typically have wings. They generally rely on native vegetation for shelter, breeding and feeding. The important role of insects is often not realised. Insects are involved in soil aeration, litter decomposition, nutrient cycling and seed distribution. Native bees and some butterflies assist pollination of native plants.
Insects are also important in natural pest control.
The wasp larvae feed on other insects and spiders. Almost all adult wasps require nectar from native flowering shrubs and will only fly about 200m from nectar bushes and trees. Ground dwelling mammals are important in harvesting and dispersing seeds of native plants, as well as in insect control. Some ground dwelling mammals can consume their own body weight in beetles and other food in a single day. Animals like echidnas and bandicoots also search in the litter and top soil for food, frequently digging holes and helping to decompose litter.
