Too Cold For Wasps?

We have had an incredibly mild week, more like summer than autumn. However, the nights have been very chilly and you cannot deny that winter is fast approaching.

Back in Kent, we went for a walk around the lanes and noticed several very sluggish, almost drunk-like wasps. The dropping temperatures cause a shift in the wasps' metabolisms and energy storage abilities. This inability to store energy can get to the point where it becomes hard to do the simple task of flying. Indeed they can have difficulty doing much of anything, dying off altogether as the temperatures drop below zero and the frosts appear.
