They frequent the night, hidden by darkness. They are noisy, yet we never hear them. They gobble up those we dislike.
They are the microbats.
These little bats may look like small versions of the more familiar megabats, or flying foxes, but they are very different.
The megabats get their name in part due to their size. For example, the common species seen in Melbourne, the grey-headed flying fox, has a body length around 25cm, a wingspan about 1m, and weighs up to 1kg.
