Yellowjacket Facts & Information

What do yellowjackets look like?

Yellowjackets are small to medium-sized wasps, usually ranging from 0.5 to 0.75 inches in length. They have a distinctive black-and-yellow striped body that gives them a striking appearance. Their smooth, slender bodies are equipped with narrow waists and long legs, making them agile flyers.

What do yellowjackets eat?

Yellowjackets are omnivorous and have a diverse diet. They primarily feed on sugary substances such as nectar, fruit juices, and human food, especially during late summer and early fall. They are also scavengers and play a role in pest control by preying on other insects, including flies and caterpillars.

What sort of habitat do yellowjackets live in?

Yellowjackets typically build their nests in sheltered locations such as underground burrows, wall voids, and tree cavities. Their nests are made from a papery substance created by chewing wood fibers mixed with saliva, resulting in a rounded, often hidden structure that can house thousands of individuals.

How do yellowjackets commonly behave?

Yellowjackets are social insects that live in colonies, which can number in the thousands. They are known for their aggressive behavior, especially when their nests are disturbed. Unlike some other wasps, yellowjackets can sting multiple times, and they are often drawn to human food, making them a common nuisance at picnics and outdoor events.

Did you know this about yellowjackets?

Yellowjackets are important for the ecosystem, as they help control pest populations and are effective pollinators. Interestingly, their aggressive nature is often misunderstood; they are more likely to sting when defending their nest or when attracted to food sources. Despite their reputation, yellowjackets can be fascinating to observe, especially their complex social structures and hunting behaviors.
