Hoverflies are sometimes referred to as flower Flies and will be seen hovering at flowers. They mainly feed on pollen and nectar. Hoverflies are known to mimic bees and wasps as a defence against predators. They are common in most countries.
They are commonly seen during warmer months hovering among flowers, feeding and mating. They pollinate many plants and help keep aphids under control.
They will hover in the one spot, then move suddenly forwards or sideways, hovering again.
