This is a common hoverfly, whose larvae feed on aphids. It is a wasp mimic. It is commonly found in wooded areas and most prefers feeding from umbellifers such as Wild Carrot, as well as Common Ivy. As with all hoverflies, despite its colouration, it does not sting.
The common English name ‘Batman Hoverfly’ is due to the pattern on this hoverfly’s thorax.
