There are fig wasps, of course. And other species, yes, that aren’t quite as good as bees at pollinating, but neither are butterflies, but no one has a problem with labeling them as pollinators. Plus there are the wasps that eradicate pests. The year I had a paper wasp family move in near my garden was a bumper year for my brassicas, because they absolutely annihilated the cabbage white caterpillar population. Basically, wasps aren’t just useless enemies.
