Breeding of Dragonflies in Temporary Waters
Abstract
THROUGHOUT Western Australia there are five or more consecutive months in which there is little or no rain. Over the greater part of the State the mean annual rainfall is less than 20 in., derived mainly from a few heavy falls. The surface-waters which result from these rains usually persist for a few months at the most; there are very few permanent, natural fresh waters. In the south-west (as at Perth), the rainfall exceeds 35 in. and is derived from more frequent lighter falls, but even here many of the surface-waters dry up from about November until April or May.
