Are there a lot of these? It could be a queen breaking down and failing to fertilize eggs laid in worker cells. Those appear way too big. If it is a couple it is not a big problem, if it is a sizable number, you need a new queen.

Slow down Lab, the experts are conjecturing. I still bet if it is just a couple not moving larvaie like critters more than filling a worker cell, it is a drone/unfertilized egg hatchling mislaid by the queen. If it is just an occasional, no need to worry. If you need practice worrying, please continue.
