Internet users know what they want and today, when they're not searching for info on celebrities and magazines about celebrities, they're doing Internet searches for "ovipositors."
What's an ovipositor? The simple answer is that it's an egg-laying organ generally located on the tail end of an insect's abdomen. But ovipositors are far more than mere insect reproductive organs. Ovipositors have evolved to keep pace with the needs of their owners to place eggs in ever-more-secure or beneficial locations. For this reason, cicadas and grasshoppers developed spiked ovipositors to better deposit their young in the ground or in the stems of plants.
Wasps took this concept even further, as their ovipositors are tailor-made to pierce the carapaces of other living creatures, thus laying their precious offspring inside their first meal. They even evolved to offer a venomous punch, so as to subdue their victim for this brutal surgery.
Of course, we tend to call such ovipositors "stingers." This is why only female bees and wasps can dish out any pain. While bees long ago traded laying eggs inside enemy larva for the wonders of their honey-filled hives, their stingers still pack a serious punch.
