Just kind of twisting and turning and doodling around, upside down with their chins against the lid. Looks a LOT like what Stevie does when he's "in the zone".

My bee (and a few others) look like that when they are trying to push the "lid" off, even though my tubs are in a lidless rack. The shaking is actually them exerting themselves to push. I only see it during feeding time or when they are very active at night.
