👉 Apoidea is a phylum composed of animals that share a common ancestor with insects, including ants, flies, and spiders. They are known for their highly specialized structures, such as exoskeletons, gills, and eyes, which aid in their adaptation to living in aquatic environments. Apoidea includes many species that play vital roles in the food chain, from pollinators like bees and butterflies to decomposers like decaying plants.
