Wasps are very important pollinators. Wasps are insects in the same Order, Hymenoptera, as bees and ants. Wasps, like bees, have very high-energy needs that must be met for their survival. the vast majority of wasps are carnivorous. However, these wasps cannot survive based on a completely meat-diet; they in fact need to supplement their diets with sugar and water, which very often comes from flower nectar, or honeydew produced by insect herbivores (e.g., aphids).Wasps need key resources such as pollen and nectar from a variety of flowers. Even though they don’t collect pollen, they do visit flowers constantly to seek nectar for their own energy. As wasps visit these flowers, they inadvertently transfer pollen from plant to plant. Although this is a less efficient form of pollination, it is still quite impactful to our ecosystem. Read more about wasps as pollinators at this link.
The best-known pollinators are bees and butterflies, but there are other pollinators that don’t get enough credit for their assistance with pollination. Moths, in particular, are not only forgotten pollinators, but they are also a critical part of the food web. Unfortunately, moth species are in serious decline due to habitat loss and pesticide use. Amid widespread concern about the decline of wild pollinating insects like bees and butterflies Researchers that moths are more efficient pollinators than day-flying insects such as bees, which are traditionally thought of as ‘hard-working’. While day-flying insects have more time available to transfer pollen, moths are making an important contribution during the short hours of darkness. You can learn more about moths here.
Beetles compose the largest group of living beings on Earth. There are some beetles that pollinate plants by accident, because they feed on pollen, but they are not specially equipped for this task. Read more here about beetles as pollinators.
