Are Wasps Always Yellow?
WouterDepending on the species, wasps can be found in a variety of colors. They are scavengers, eating insects and other pests. Some species scavenge for protein-rich foods, while others scavenge for sugars and sweets.
Some species are eusocial, meaning that they live in colonies. Their colonies can be as large as 15,000 wasps. Each colony begins with a single reproductive female. These females lay eggs that provide food for the larvae. As the larvae mature, they become workers. They are then driven away from the nest by the foundress. This leads to an exodus of starving larvae.
Several species of yellowjackets construct nests under eaves or in tree hollows. They also build nests in wall voids, bushes, and sheds. Some species scavenge at meat-packing plants and carrion for protein.
Yellow jackets are scavengers and predators. They often attack people near their nests. They sting and bite. If you are stung by these wasps, stay away from the nest and seek professional help.
Paper wasps are small, slender wasps. They build nests that resemble an upside-down umbrella. These nests are typically found in the eaves of picnic shelters and other structures.
Mud-dauber wasps are about the same size as paper wasps. They also build mud nests. These wasps are common in moist areas. They also stockpile spiders in their nests.
The Polistes genus is the largest genus within the family Vespidae. These wasps are found in large numbers in Arizona. These wasps have triangular faces and long legs that dangle below their bodies.
