Wasps always seem like such angry insects to me. Maybe it is because they're all hard angles and stingers, I can't rightly be sure but they aren't friendly like bees. Perhaps it is because they don't produce honey so there is no sweetness to them. Or possibly because there are parasitic wasps who do awful things to other insects. Could it be that bees die after they sting so there is an element of sacrifice whereas wasps have the ability to attack repeatedly? Maybe it is all those things but Mr. Grumpypants here found the morning chilly enough not to both chasing me off.
