Yes, wasps are good pollinators. Wasps are insects in the same order as bees and ants, called Hymenoptera. They pollinate flowers they visit, just like bees. Although most species don't pollinate plants because they don't have the soft hairs or special body part for pollen storage that bees have, wasps are attracted to nectar and carry out a useful amount of pollination in the garden.
Studies have shown that wasps can even step up and pollinate plants when bees are absent. For example, great black wasps are solitary wasps responsible for some pollination in Minnesota.
Wasps also play a key role in controlling harmful or invasive insects. If wasps went extinct, it would disrupt the delicate balance of our ecosystem, leading to negative consequences such as overpopulation of other insects and loss of pollinator species.
