Is a flying insect more closely related to a worm or a bird why?

A flying insect is more closely related to a bird than to a worm because both insects and birds are part of the phylum Ecdysozoa, which includes arthropods and vertebrates, while worms belong to the phylum Annelida. Insects and birds share a more recent common ancestor in the evolutionary tree, specifically within the clade of bilaterians. Additionally, both insects and birds are part of the larger group of organisms that exhibit bilateral symmetry and have similar developmental patterns, unlike worms which have distinct features and evolutionary paths.
