Ephemeroptera (surely, this ID can be narrowed down – suggestions welcome) Size: 8 mm I find the silhouette of these primordial creatures hard to resist. They have a reputation of being short-lived and indeed they don't live long as adults. Like many other insects the life-span of mayflies changes drastically if you consider the time they spend as larvae. Focus stacked from 32 natural light exposures in Zerene Stacker.
