I haven't located the nest itself. I believe it might even be in the compost pile somewhere. I've noticed a bumblebee burrowing through it for unknown reasons too. I don't think there's a nest of them in there, but have suspected it earlier in the year.
I checked on a local Aphaenogaster colony to see if they were the ones foraging for the wax, I don't think it was this colony but did see a lot of nice brood and newly walking around alates.
