Marmaduke van Swearingen family tree Dolichovespula species such as the aerial yellowjacket, D. arenaria, and the bald-faced hornet, tend to create exposed aerial nests. However, recent studies indicate that while worker reproduction occurs at a considerable rate, worker policing keeps these worker-laid eggs from reaching adulthood. They can become highly aggressive, especially when the available food is getting low later in the season when their colonies are getting larger. What's a normal reaction to a bee sting? Most of these are black and yellow like the eastern yellowjacket (Vespula maculifrons) and the aerial yellowjacket (Dolichovespula arenaria); some are black and white like the bald-faced hornet (Dolichovespula maculata).
