From my backyard:
The Common Green Lacewing (Chrysoperla carnea s.l.; Chrysopidae; Neuroptera; Gemeine Florfliege) poses an ID problem: Four species, Ch. mediterranea, Ch. carnea, Ch. lucasina, Ch. kolthoffi are morphologically too similar to be identified by simple means: we talk about the Ch. carnea-group or Ch. carnea sensu lato.

Ernst Mayr wrote a seminal book in 1942. Systematics and the Origin of Species. Columbia Univ. Press, N.Y. In it he describes the different ways a given species can split up into several new species. Sympatric speciation is a tough nut to crack even today. Lacewings provide some candidates: imagine a single mutation in some individuals that changes the behaviour of Lacewings from copulating at dusk to copulating at dawn. By this single mutation the existing population would be split into two genetically isolated subpopulations. Differential adaptation and morphological distinctions would come later.

You may not like the black background in the shot. But it sure as hell puts the transparent green animal on the stage. It sits on Pastinak but Chrysopa species are carnivorous when adult.
