What is a "yellow jacket"?

A yellow jacket is a type of wasp characterized by its yellow and black striped abdomen, typically found in colonies and known for its aggressive behavior, especially when its nest is threatened. They are commonly encountered during the summer months and can deliver painful stings. Yellow jackets are social insects that build nests in various locations, such as underground burrows, tree hollows, or man-made structures. They are attracted to sugary foods and can be a nuisance at outdoor gatherings or picnics.
