I found this queen in Kingston about 2 weeks ago. She is the only specimen of this colouration I've ever seen. Her mesosoma is so dark you can barely make out the pattern. Below is a comparison of what all my other C. novaeboracensis queens look like. She has eggs so I'm excited to see if this trait carries over to the workers.
Here is what all my other queens look like.
