Common Darters are widespread across the UK and can fly throughout the Summer, and even into December if it’s mild enough. They are easily missed due to their small size, but a real treat if you can get up close, like this one I spotted on a gate at Moor Green Lakes in Finchampstead.
The females have a dusky yellow abdomen whilst the males are orange-red. The colours have faded on this older male, although it still retains the two yellow patches separated by a reddish-brown blotch on the side of it’s thorax. If you’ve got a patience and a eye for detail, you can even confirm the species of darter from the eye colours! – Here green with black spots and brown on top.
