Are you in Perth? I noticed the annual fly plague has begun.

"Perth

Bush flies are first noticeable in October. The numbers rise steeply in November. They peak in December (when people and food can be covered with bush flies at December barbecues).

After the peak, the numbers fall off fast. By the end of January, almost all the bush flies are gone. (This sharp peak and sharp drop-off only happens in the south-west of Australia. In the south-east, the bush flies linger until March.)

The pattern in Perth is very regular. To the north-east, there's a large amount of agricultural land with a climate where bush flies survive the winter and breed all year, with the breeding rate depending on the temperature. By September, breeding increases rapidly because of higher temperatures and drier weather. Temperatures are also high enough for large numbers of pregnant female flies to move south-west on north-easterly winds. They then breed in the rich cow dung in the southern pasture-lands.

Rising temperatures during October and November hatch out the young flies and these breed in the same southern pastures. A kind of chain-reaction takes place, and the bush-fly population rises to a characteristically sharp peak in December.

By the end of December, the dung quality declines because hot, dry weather dries out the pastures. Breeding slows down, and the survival rate of larvae also drops sharply. By the end of January, it's all over: near the coast, where most of the people live, there are hardly any more bush flies."
