There are a few species of paper wasps in Alameda County. Their nests have been compared to upside down umbrellas with many holes arranged in a geometric pattern. These wasp nests are usually found under eaves or sheltered patio areas. The European paper wasp is the most commonly encountered paper wasp in Alameda County. They look much like the yellow jackets commonly found here, except the body is slimmer and longer with orange colored legs and antennae. While flying the legs dangle rather than being held close to the body like a yellow jacket.
