Bees buzzed in the long grass around the lake as evening fell. To Frank’s delight, they were settling down in little rows along the stems. These were solitary bees, probably males, gathering for the night in suitable resting places, while the females occupied nests they had built nearby.
Being cold-blooded, bees gain energy from the sun’s heat and rest at night and during cool weather. Holding tight to the stems with their strong, jaw-like mandibles, they gradually relax – their bodies lower, their wings rest and their antennae droop – until they fall asleep, waiting for the morning to come.
