Marsh hoverfly - The Footballer

This colourful character is one of the marsh hoverflies.  It's scientific name is Helophilus which means marsh-lover.  It spends a lot of time sunbathing on foliage near water and so it is sometimes called the Sunfly. 

But in its colourful stripy jersey it is also known as The Footballer.  If you disturb it, it flies around with a loud buzz before settling back on another leaf.
