Half a league, half a league, Half a league onward, All in the valley of Death   Rode the six hundred.

For some reason I think that Tennyson was imagining that the six hundred were riding Perilampids, I mean, wouldn't you?  This stead is Euperilampus triangularis from western Maryland. #perilampid #wasps #wasp #metallica #tennyson

A perilampid (Euperilampus triangularis).  Tiny little metallic armored knights.  Really tiny, only a couple of millimetres.  You can find them in the wilds of vegetation if you hunker down and look inside the grass and forb canopy of fields, where they sit upon leaves like little blue teardrops.  Hyperparasite of other parasitic larvae living inside a host like a caterpillar.  After hatching on the vegetation their little vaguely silverfish like larvae find a host that has been attacked by another bigger parasite burrows in and finds the other parasitic larvae and parasitises the primary parasite of the host not the host itself.  Nature can be tricky. ... and beautiful.
