Are ants arachnids

Ants are social insects of the family Formicidaeand, along with the related families of wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago and diversified after the rise of flowering plants. Today, more than 12,000 species are classified with upper estimates of about 14,000 species.[3][4] They are easily identified by their elbowed antennae and a distinctive node-like structure that forms a slender waist.
