That's all. One wasp. I hope that this season doesn't produce as many wasps as the last season did.
The evidence on the floor of Hive E pointed to an occupation. That is exactly what has happened. At some point in the last few days a swarm has occupied Hive E. Welcome to Colony 12.
The signs that this was not a robbery included detritus which looked too dark to be from capped honey. That was a sign. The most striking thing though was the Wax Moth larvae. An infestation of Wax Moth must have been under way because there were 3 or 4 larvae on both times I looked.
I'm happy to say that my transfer of Colony 11 from its nucleus box to Hive C have been successful. There is pollen on the hive floor; debris from cleaning of the framed comb and evidence of new comb building. There was also lots of activity at the hive entrance.
The less welcome news is that the comb building is happening beneath the nuc' box lid. I had hoped that they would move onto the framed comb and leave the lid area alone. That hasn't happened so I'll have to do something a bit more destructive to sort the hive out so that it has only framed comb in it.
