Urban Observation of the Week: Pool Foam Wasp’s Nest

It can be super scary to see a wasp nest in your neighborhood. Wasps can cause a very painful sting. Sometimes their nests can cause damage to your property too. But these critters also provide important ecosystem services – they help control pest insects and pollinate flowers!

You may have heard of birds making nests out of trash, but what about a wasp using trash to build it’s nest??? iNaturalist user rose21 documented this wasp using a bit of rubbish for her nest. It was an iNaturalist observation of the week a few weeks back and we have to agree that this is a pretty interesting observation!


Do you have a photo or video of an urban species doing something unusual? What about a rare plant or animal that you were surprised to find in a city? If so, let Lindsay know or Tweet at us and you could be featured as a future observation of the week!

  1. I found a nest like this, figured it must be a matter of materials rather than a particular species. Even came down to the same source material as this article, except that the foam was from a trampoline padding, never thought of that until I saw this article
