va grows a bit, it plunges into the spider's body and feeds voraciously, avoiding vital organs for as long as possible to keep it fresh. After completing pupation the adult wasp emerges from the nest. Tarantula wasps feed primarily on nectar and other natural sugary materials. The consumption of fermented fruit sometimes intoxicates them to the point that flight becomes difficult. While the wasps tend to be most active in daytime summer months, they avoid the very highest temperatures. The male tarantula hawk does not hunt; instead, it feeds off the flowers of milkweeds, western soapberry trees, or mesquite trees. The male tarantula hawk has a behavior called "hill-topping", where he sits atop tall plants and watches for females that are ready to reproduce.

The tarantula hawk is relatively docile and rarely stings without provocation. The sting, particularly of Pepsis formosa, is among the most painful of any insect, but the intense pain only lasts for about 3 minutes.[ Commenting on his own experience, one researcher described the pain as "…immediate, excruciating pain that simply shuts down one's ability to do anything, except, perhaps, scream. Mental discipline simply does not work in these situations”. In terms of scale, the wasp's sting is rated near the top of the Schmidt Sting Pain Index, second only to that of the bullet ant and is described by Schmidt as "blinding, fierce [and] shockingly electric". Because of their extremely large stingers, very few animals are able to eat them; one of the few animals that can is the roadrunner.
The U.S. State of New Mexico chose the insect in 1989 to become its official state insect. The selection of the insect was prompted by a group of Edgewood, New Mexico, elementary school children doing research on states which had adopted state insects. They selected three insects as candidates, and mailed ballots to all schools for a state wide electio
