This posting was inspired by Myrmecos, a general lack of inspiration, and just wondering what a 500 pixel wide microarthropod might look like. Although there are some long, lean mites that might be more appropriate, Prolixus forsteri comes to mind, or perhaps the unbeatable long lean acarine, Gordialycus tuzetae Coineau, Fize & Deboutteville 1967 – which looks more like a giant nematode than a worm (for a light micrograph see*), alas, I have no pictures of them.
Really, I’m just tired of shovelling snow (~20 cm today, and it is well into May) and ready to veg out in front of the most recent Circus of the Spineless, so here’s one of my larger contributions, a ~ 3 mm long Parajapyx species from Queensland (where snows are few and far between). Not much seems to be known about these mini-diplurans. The monstrous Heterojapyx (~ 20 mm) make better pets, especially if you enjoy watching them catching collembolans with their posterior pinchers, twisting around their abdomens, and then eating the RSPCAless springtails alive, but are far too large to contemplate for the SEM.
