They can be seen all year round but are most numerous in late summer.
We found that we would see a few stray beetles around the garden and believe them to be scouts. Found in northern Australia; particularly in northern NSW, the Northern Territory and throughout Queensland. They are present in fruit growing areas and where sugar cane is grown. It doesn’t seem to be such a pest in cooler areas. They are in all but the most southern states.
Although these areas are tropical and sub-tropical this beetle likes a warm, dry climate. A hot dry spell seems to be when the eggs are laid and following heavy rainfall (typical of tropical climates), the adults emerge, although we have seen swarms when the dry weather is prolonged.
