Wasps in the woodpile

I lit the wood-burning stove for the first time last weekend and when I went to get the logs I found a hibernating queen wasp on the first one.

Two logs later I found these two tucked up side by side.

All three are common wasps (Vespula vulgaris).  Notice how their antennae are folded and tucked inside their front legs and their wings are collapsed and tucked inside the back legs for protection.  The weather has been pretty mild recently so I am interested that they are asleep already.  Thinking about it I suppose there isn't much to eat or much to do so they may as well turn in early.  I don't know if it was a bad year for wasps but there have been very few around the hives this year.
