Tarantula hawk
Pepsis
The female tarantula hawk wasp stings a tarantula between the legs, paralyzing it, and then drags the prey to a specially prepared burrow, where a single egg is laid on the tarantula's abdomen, and the burrow entrance is covered. Sex of offspring is determined by fertilization; fertilized eggs produce females, while unfertilized eggs produce males. When the wasp larva hatches, it creates a small hole in the spider's abdomen, then enters and feeds voraciously, avoiding vital organs for as long as possible to keep the tarantula alive. After several weeks, the larva pupates. Finally, the wasp becomes an adult and emerges from the tarantula's abdomen to continue the life cycle.
Adult tarantula hawks are nectarivorous. While the wasps tend to be most active in the daytime in summer, they tend to avoid high temperatures. The male tarantula hawk does not hunt. Both males and females feed on the flowers. Male tarantula hawks have been observed practicing a behavior called hill-topping, in which they sit atop tall plants and watch for passing females ready to reproduce. The males can become resident defenders of the favorable reproduction spots for hours into the afternoon. Females are not very aggressive, in that they are hesitant to sting, but the sting is extraordinarily painful.
