The Batman hoverfly is commonly found in wooded areas across the UK and will visit gardens. They feed on the pollen and nectar of a range of flowers, from blackthorn in spring to umbellifers in summer and ivy in autumn. Look out for them basking on leaves or hovering in sunbeams. Their aquatic larvae develop in water-filled holes and crevices in trees, but adults can lay eggs in just about any container with some standing water. They've even been known to use compost and wet cow dung. If you create a hoverfly lagoon in your garden, there's a good chance you'll attract this species.
