The primary classification for the Black widow spider is indeed "Non Insect." This classification is because spiders belong to the class Arachnida, which is distinct from the class Insecta. Arachnids include not only spiders but also scorpions, mites, and ticks, and they are characterized by having eight legs, body segments that include a cephalothorax and abdomen, and no antennae, unlike insects which have six legs and a different body structure.

The other classifications mentioned, such as Ametabolous and Hemimetabolous, pertain to types of insect development. Ametabolous refers to insects that undergo very little change from immature to adult stages, while Hemimetabolous denotes insects that undergo incomplete metamorphosis, like grasshoppers and cockroaches. Since the Black widow spider is not an insect and does not undergo these types of metamorphosis, "Non Insect" is the correct and most fitting classification.
