Biting insects at Palmerston fall into three main groups : Culicidae (Mosquitoes); Culicoides (Biting Midges) and Tabanidae (March Flies). The March flies appear to be a relatively minor problem near some areas of the mangrove margin in the early wet season. The other two groups are more prominent and may occur at times
in significant pest levels. A separate report has been prepared dealing with the biting midges and this report will cover only mosquitoes.
