Hello Gardeners, I’m Amanda McNulty with Clemson Extension and Making It Grow. Bees and wasps and hornets are in the same family, Hymenoptera, but have certain differences. In all cases, only the females can sting, as the egg-laying ovipositor also functions as the stinger. The female bees also are the sex which collects pollen, either in special structures called corbiculae, or in hairs on their bodies. For bees, pollen collection is necessary as bees make a mixture of pollen and nectar which serves as the food source for their young.
