I'm another biology nerd, and I agree. I've always had a live-and-let-live policy with most critters, and I feel rewarded by the diversity of life on my little place. Like Expat said, as a gardener, I love it when I see wasps getting cabbage worms and asparagus worms. We'll mostly give them space when they set up a nest, but I'll also take a nest down and kill the momma if it's in a bad spot or if they decide to cop an attitude.As a natural history professional, gotta put my 2 cents in.
All these hymenopterans are pollinators, and were doing the job long before honeybees got here. They also do great damage to garden and farm pests, especially caterpillars. If you are allergic, I understand your reaction. But I never harm them unless they pose a direct hazard to people.
Late summer/fall can be a problem. Usually they are programmed to defend the nest, but as the year gets later, their social order begins to break down, and they start defending personal space more (especially yellowjackets). They will go after your pop (for themselves) and your chicken sandwich (for the babies), and don't care who gets hurt in the process.
Those are grasshoppersI don't thing I've ever seen the yellow faced wasps before?
