Solitary wasps are a diverse group of insects that do not live in colonies like social wasps. Instead, each female wasp builds her own nest, lays eggs, and provides food for her young. They are often found in gardens and natural habitats, where they play a crucial role in pollination and pest control. Unlike social wasps, solitary wasps do not have a queen or workers. They typically hunt for insects, such as caterpillars or spiders, to feed their larvae. These wasps are generally non-aggressive and only sting when threatened, making them beneficial for the ecosystem.
