"that crunchy part's the thorax"


i'm obsessed w/ this pepsis wasp now, a.k.a, the tarantula hawk. first of all, they're beautiful. second, they get drunk off fermented fruit. but the real clincher for me is what it does to tarantulas. get a load of this madness:

A female wasp finds a tarantula by smell. Generally, she scampers across the ground to locate a burrow. She will enter the burrow and expel the spider, then attack it. She may also encounter a male tarantula during his search for a mate. In an attack, the wasp uses her antennae to probe the spider, which may raise its front legs and bare its fangs. (A tarantula does not always counterattack.) She then attempts to sting the spider. She might seize the spider by a leg, flip it over on its back and sting it, or she may approach from the side to deliver a sting. Once stung, the tarantula becomes paralyzed within seconds. The condition will last for the remainder of its life. The wasp may drink the body fluids oozing from the spider’s wounds or from its mouth to replenish nutrients and water she used during the attack.

If the wasp expelled her victim, she will drag it back into its own burrow, now a burial vault, lay a single egg on the spider’s abdomen, then seal the chamber. If the wasp succeeds in stinging a male tarantula on a mating hunt, she will excavate a burrow, drag the paralyzed spider inside, lay her single egg, and seal the chamber.

Once the egg hatches, the tiny grub, initially connected to the spider by the tip of its tail, bends over, attaches its head and begins to suck. It continues sucking until its final moult. It then rips open the spider's abdomen, thrusts its head and part of the thorax inside, and "feeds ravenously," as one entomologist described it. As one might hope, even for a spider, the tarantula at this point is finally dead.
remember that the next time someone uses "it's natural" to justify something. now for some videos:



the fight



the kill



the schlep.

be sure to watch these before you go to sleep. (next to a feather duster that will lightly graze your arm as you nod off, causing you to jolt up in abject arm-flailing hysteria.)
