Final answer:
Paper wasps and yellow jackets differ in appearance, with wasps having longer bodies and open nests, compared to the yellow jackets' shorter, robust bodies and enclosed nests. Yellow jackets tend to be more aggressive, particularly near food sources, while paper wasps are less so unless their nests are disturbed.
Step-by-step explanation:
Difference Between Paper Wasps vs Yellow Jackets
The main differences between paper wasps and yellow jackets lie in their physical appearance, nesting habits, and behavior. Paper wasps tend to have longer bodies and legs, a narrow waist, and appear somewhat slimmer than yellow jackets. Their nests are usually open and suspended from structures like eaves or branches. In contrast, yellow jackets have a more robust and shorter body with a banded yellow and black color pattern that is often brighter than that of paper wasps. Yellow jacket nests are typically found in concealed spaces such as rodent burrows or cavities in walls, and they are enclosed with a papery substance.
When it comes to behavior, paper wasps are generally less aggressive and will only attack if their nest is disturbed. Conversely, yellow jackets can be very aggressive, especially in the presence of food, and may sting multiple times. Additionally, yellow jackets are commonly seen hovering near garbage disposal areas and outdoor eating spaces during later summer and fall when they are searching for food, whereas paper wasps are not as commonly found in these areas. Knowing the distinction between these two species can be useful for safely managing encounters with them.
