For some weeks now, the walls around the outside lights of Colombo Village have been graced with an abundance of mayflies as well as some other insects (lots of crane flies, a few moths, an occasional beetle). I finally got around to photographing the mayflies a couple of days ago. The upper photograph is a fully mature male; the lower photograph is a female (a subadult — what the anglers call a 'dun' — I think). Note the difference in the eyes.
Mayflies are among the oldest groups of insects and are the only insects to have two adult stages with fully developed wings.
