Wasps are known for their painful sting, which they use as a defense mechanism against threats. Unlike bees, which typically sting only once before dying, wasps can sting multiple times, making them more formidable in protecting their nests. Wasps play a beneficial role in ecosystems, as many species are predators of pest insects, helping control their populations. Additionally, some wasps are pollinators, contributing to the reproduction of plants. Despite their fearsome reputation, wasps are an important part of the natural world, balancing insect populations and supporting plant life.
