Something went wrong with this colony. I can't see any workers in the tunnels anymore. The queen is still there, but I think the colony is in a bad way. I'm not going to mess around with dirt setups anymore.
Are they still in diapause? These gals love to pile onto each other and condense to as small as they possibly can during the winter. Maybe they're just hiding?
Worst case, it is spring time and colonies will be keeping their queens and brood fairly shallow. You could always place a flat stone over a mound, wait a week and flip it to collect a queen and a few dozen to a hundred workers. Not an ideal situation, but it'll do til flights arrive in July.
