bombus terrestris (buff tailed bumblebee) autumn nest

[robomantis]

I would love to see an older mature nest in fall. How did you find this nest?

@robomantis Hi Rob, A friend of mine spotted it. Amazingly it's still active now...and there's another one nearby. It is not as uncommon as I thought for b. terrestris to produce a second brood through the winter.
