After hiking for a couple hours through a park it’s often nice to stop and take break, resting in one of the open wooden shelters found in many parks. When you do, if you look up, you just might see one or more paper wasp nests. Perhaps you’ll even see a nest currently occupied with busy wasps going about raising their next generation.
If you look closely at some of the photos (click on them for a larger view) you may see young larvae in the open cells. The queen lays eggs in open cells, which mature into larvae. These larvae will eventually spin a cocoon in the cell, also visible in some of the photos. They will enter the pupal stage in the cocoon, after which they’ll emerge as adult wasps. It’s a fascinating life cycle.
Be careful if you do find active nests. Though I’ve never had any problems with wasps, they can be very protective of their nests, attacking if they feel threatened. Best to leave them be, and maybe not stand quite as tall as you normally would if the shelter has a low ceiling. Sometimes I’ll just sit in a corner and watch (and photograph) the wasps as they go about their day. Very interesting and social creatures.
Next time you rest in an open shelter, look up. What do you see?
