Posted by Green Day In Seattle , 07 November 2012 · 1,874 views

So... I haven't really posted anything in a while. Sorry about that for any of the few people who actually pay attention to this blog. I've had soooo much school work! it's been crazy! Anyway, I'm gonna do another entry now that I have a little break!

The Arizona Bark Scorpion (Centruroides sculpturatus) is a tiny scorpion found in, well, Arizona. It lives in the Sonoran desert and is mostly active at night when it hunts crickets, beetles, and other small insects which it ambushes from a dug out burrow. This little guy only reaches a maximum length of about three inches and is very light brown in color. During the day, it hides in the shade or buries itself in sand to avoid the sunlight. It's often found under rocks, in crevices, bark, leaf litter, and can sometimes find its way into dark places in houses or shoes. During the winter, many bark scorpions will come together to form packs. This is extremely unusual as almost all other species of scorpion are strictly solitary.

As with most scorpions, the Arizona Bark scorpion is fluorescent when exposed to ultra violet light. They are easy to locate wandering around at night in desert because of this.

Bark scorpions live for about six years and are sexually mature after one. Females give birth to live young instead of laying eggs. The baby scorpions are exact miniatures of the adult and stay with the mother scorpion, riding around on her back, until their first molt. Litter sizes can range from twenty five to thirty five babies.

This scorpion is not generally aggressive, but it will become so if it feels threatened as with any wild animal. Its first instinct is to get away, but if that fails, the sting is very painful and can be quite dangerous. Although not normally fatal, stings can lead to temporary paralysis and possibly convulsions on whatever portion of the body was stung. Arizona Barks are the most venomous scorpion in North America and stings should always receive adequate medical attention such as an injection of antivenom. Stings have been described by victims as feeling like continuous jolts of electricity after envenomation.

If you ever happen to run across an Arizona Bark scorpion, don't mess with it or kill it, just whip out your blacklight (which I'm sure all of you have and carry around with you at all times, right?), stand back and enjoy it. Scorpions are very interesting and unique arachnids and should be treated with the respect they deserve.
