We get so many wasps. All natives (except the harmless paper wasp) are hunters of spiders and caterpillars that they cart off to their nests or build clay incubators on the walls and stuff with paralysed arachnids or caterpillars to snack on whilst growing. I’ve recorded at least 20 species here from Hornets about 5cm long to tiny black ichneumon wasps less than 2mm. None of them pay any attention to me, the only time I get attention is if I disturb the yellow and black wasps nesting sites. They live in colonies of up to 20 or so and can sting. Not the european wasps which are a pest here and are waged war on without mercy if you see them.
Seeing a 1cm black ichneumon take on a spider 3 times her size is amazing. Watching the black and yellows take off with dangling green caterpillars…awesome.
It took me 3 years to get a balance in the garden but now the pests are controlled (except the fucking slugs and bastard fucking fruitfly) by natural predators, who are also fascinating to watch.
