Arrowhead Borer
The arrowhead borer, or the pine Bark runner, is also a member of the beetle family. They are usually found on the bark of fire ravages or damaged pines, and guess what? They run faster than Usain Bolt! Okay, that was an exaggeration, but I am sure you get the point. They run so fast that they are often mistaken for crickets.
Apart from the scary hairs protruding from their bodies, the arrowhead borer can sometimes be found with pseudoscorpions attached to its hind legs. The thrill of a fast car ride excites humans, so who says scorpions do not like to be daredevils too? Before you ask, the arrowhead borer is not affected in any way because they practice a commensalism relationship with a scorpion. In other words, the scorpions benefit while the arrowhead remains unaffected.
