Mexican grass-carrying wasp are solitary wasps known for their unique nesting behavior in hollow stems or man-made structures, favoring sunny habitats. They display striking behaviors such as provisioning their nests with paralyzed orthopterans to feed their developing young, a testament to their role as natural pest controllers. Distinctly, during larval development, individuals undergo complete metamorphosis, showcasing the marvels of insect development from larvae to winged adults.

Isodontia elegans is a species of thread-waisted wasp in the family Sphecidae that hunt orthopterans.

Isodontia philadelphica is a species of thread-waisted wasp in the family Sphecidae.

Thread-waisted wasps (Eremnophila aureonotata) are dutiful parents that spend a great deal of time finding meals for their future children. They sting their prey in order to paralyze them. These insects will bury paralyzed caterpillars in burrows where their larva will feed on them over time. A cruel fate for the unfortunate souls who are captured.

The species name Caementarium is Latin for "mason", which comes from the black and yellow mud dauber's practice of building nests out of mud. The female wasps prey on spiders, fill cells of the nest with both the prey and her eggs, and leave the nest when it is full. When the larvae hatch, they eat the prey and leave the nest as well.

With a penchant for warm environments, sceliphron madraspatanum crafts its nest from mud, meticulously shaping individual cells to accommodate its offspring. In a fascinating display of maternal investment, this solitary architect uses its stinger to paralyze spiders, providing a living feast for its larvae, ensuring a fresh food source upon hatching. The sleek, elongated abdomen of this creature is a marvel, complemented by wings that carry it swiftly on its quest for construction materials and prey.

In its metallic blue shimmer, japanese blue mud-dauber wasp is an adept aerial hunter, with impressive proficiency in capturing and paralyzing its prey, spiders, to feed its offspring. This remarkable wasp is also known for its peculiar habit of usurping the nests of other mud daubers to rear its young, an exceptional display of resourcefulness in the insect world.

The blue Mud Wasp (Chalybion californicum) is a brilliantly colored blue wasp that is a preditor for black widows. They sting and paralyze the subject before eating them, which controls the spider population. These wasps reuse the nests of other wasps, inserting paralyzed spiders to feed on over the winter.
