Just outside our kitchen window are the lower branches of a pignut hickory tree. The leaves are typical for hickory in June - bright green, compound, and in pretty good condition, but nothing showy or unusual. Often, when I look out the window, I see a wasp or two flying in and out of the leaves, seeming to inspect them top and bottom.
A few years ago I would have freaked out a bit. Where was the wasp nest? Would I get stung as I was changing out the hummingbird feeder water or emptying and refilling the small birdbath just below these branches? What is that wasp DOING out there?!
Now I relax...and quietly thank each wasp I see. Why this change in my attitude?
After living on this Earth for almost 60 years, I finally realized that wasps weren't my enemies, they were my friends. The wasps I see inspecting the hickory leaves are looking for caterpillars to paralyze and take to their nest as food for their progeny. Those very wasps are probably almost completely responsible for the fact that the hickory leaves still look good, even this early in the growing season. To my knowledge, all wasp young are raised on meat, a.k.a. caterpillars and other insects/arthropods. Some wasp species hunt cicadas, some wasp species hunt grasshoppers, some wasp species hunt spiders...and many wasp species hunt caterpillars.
It's only in defense of their nest - their eggs and young and queen - that wasps generally get nasty-tempered, and many wasps are solitary nesters, so they don't get nasty-tempered even then.
Meanwhile, the female wasps patrol our yards and gardens all day long, hunting for the caterpillars or even grasshoppers munching on our plants.
Will I happily allow a paper wasp nest to be built right outside a commonly used doorway? No. However, I do allow mud daubers to build there, since they are solitary wasps and not aggressive. Now, too, I allow paper wasp nests to be built in out-of-the-way places, although I do note carefully where they are, so I can steer clear of them.
It never ceases to amaze me how well "nature" works when we get out of its way. It's never as scary as it seems before we take the time to realize what's actually going on.
