Blue-banded bees (Amegilla cingulata) are widespread across southern Australia. These males, photographed at Margaret River in WA, are snoozing on a thistle. Each has clamped his jaws onto a stem to hold himself in place. Although normally solitary, these fellows have gathered together over a pile of sand, where several females have dug burrows. They'll be the first on site when the females emerge in the morning.
