While photographing a Sigmoid Prominent outside our Environmental Center, I noticed a series of long narrow marks along the wood siding of the building. We shared a photo of them as a quiz on our Facebook page. Do you know who made these bizarre markings?
It didn’t take long before their creator returned and continued the job:
If you guessed Bald-faced Hornet in our photo quiz, you are correct! Points will also be awarded to anyone who guessed one of the ‘paper nest wasps’ (or anything in Vespidae) as I doubt this photo is diagnostic for a single species. These wasps (they are not actually hornets) will use dead wood for constructing their large papery nests. Here is an excerpt from a PennState’s College of Agricultural Science ‘Entomological Notes’ with details on their nesting process:
The queen collects cellulose from weathered and rotting wood, chews the wood adding her saliva, and takes this paste and makes a papery material to construct the nest. She creates a few brood cells within the nest and deposits eggs in them and feeds the larvae when they hatch. This first brood will assume the duties of nest building, food collection, feeding the larvae and protecting the nest. As the summer progresses, the colony grows until there may be 100 to 400 workers.
We currently have one of these nests on display in our Discovery Room at Gilsland Farm.
