The rare Scottsdale Aquatic scorpion? afraid not…

This was weird, and sad for sure.

In previous posts, I’ve mentioned the unfortunate similarity of our swimming pool to the LaBrea Tarpits.  Especially in the summer months when there are lots of inexperienced young animals out and about, we often have to carry out water rescues.  Since my studio is at home and looks onto the pool, this is often in the nick of time: desert cottontails, house sparrow fledglings, tiger whiptails, european honeybees, beetles, moths, sunspiders, and even the occasional “cowkiller” (AKA velvet ant) have all been successfully fished out to live another day.

face-of-scorpHere’s a close-up of it, eye-to-eye, a view we don’t often see of these close to the ground tiny arthropods.  If you’re wondering how this mildly venomous stingy thing differs from the more venomous stingy-thing, the Bark Scorpion (Centuroides spp.), the thicker, bulbous tail with longitudinal stripes on each section is the easiest characteristic to note.  The Bark scorpion has a much thinner, more gracile tail and pincers, and often holds its tail coiled to the side.
