Paper wasps and their nest

I found a group of paper wasps working on a nest, on top of our porch swing.

Behind the active nest is another larger one, apparently abandoned––or maybe the young have already emerged from it.

A few days later both nests had been knocked down by some creature that probably ate the wasps and any eggs or pupae; nothing left but one dead wasp.

In North America there are 22 species of paper wasps, genus Polistes, according to Wikipedia. [More about paper wasps, including their life cycle: 1, 2, and Bugguide has photos of about 18 different species from N. America.] They are quite common around our place, and generally ignore us if we do the same. I’ve gotten stung twice this summer though: once when removing a nest made in the recess of the car door hinges; and once when I was replacing a hummingbird feeder without noticing the wasp clinging to the bottom––I touched it and was stung. (Paper wasps feed on nectar, so the hummingbird food attracts them; they also prey on caterpillars and other “garden pests” so they’re generally considered “beneficial insects” in our narrow human way of thinking.) I caused both of these incidents, so I have no gripe against the wasps, just a resolve to be more careful. As you can see, these wasps let me get quite close with the camera.

Don’t expect such tolerance from some other insects that look very similar. Hornets and yellowjackets are irascible and can sting more than once. Stings from any, including the paper wasps, can cause severe reactions (anaphylactic shock) in allergic individuals.

More good pictures of paper wasps, taken by a backyard naturalist in Michigan, are here. The common wasp builds quite large nests, also of paper, but they are spherical and the cells are not visible as they are in paper wasp nests.

And here’s something I enjoyed discovering: a bird, Pernis apivorus, which may have wasp repellent. It’s called “Honey Buzzard”, but it is not a buzzard and feeds more on wasps (adults and pupae) than on bees. It’s believed to have some chemical on its feathers that dissuade wasps from stinging!

This beauty winters in Africa and summers in Europe and Asia, so we won’t be seeing it around our house. It has a very unusual display in flight: “The most striking version of their soaring displays involves a characteristic wing quivering which looks as if the bird is clapping its wings together above its head.”

    • Tim,

      Yes, to my (layman’s) eye they do look the same! To those interested in more about this, check out the url Tim gives, and also this one, http://www.myrmecos.net/insects/Polistes2.html, which has a great photo of adults on a nest. A Monarch Butterfly newsletter at http://butterflywebsite.com/articles/monarchwatch/newsletter.cfm?n=dec2003.txt contains an article (last on the page) about this introduced species, which predates on Monarchs. In discussing the rapid spread of the species over much of the US, it says that “This is a species with a high reproductive rate, an advantage that is enhanced by the tendency to establish nests earlier than native paper wasps, to nest in cavities, and use nests from the previous season. ” I have never observed re-use of nests from the previous season, nor have I seen them in our nest boxes (put up for swallows) but will be watching for that in future. I have seen these wasps repeatedly entering very small cavities including inside the outside frames of our aluminum windows, which have openings perhaps 1/4 inch by 1/2 inch, and assume they are nesting in there.

  1. I am a visual and performance artist living in Thunder Bay Canada. I use wasp paper to create sculptural forms. The infomation on this site was fascinating! I am looking for galleries to show my work.

  2. I’d love to see photos of your work! You must be the person I always feel like I should be saving paper wasp nests for (just the small ones, not the foot-tall and larger ones). Best wishes for finding a gallery for your work.
