A taxonomic group of insects with stinging apparatus, including wasps, ants, and bees; insects with needle-like structures.
From Latin aculeatus, meaning 'having prickles or stings,' from aculeus ('needle/sting'). The -ata ending is used in scientific taxonomy.
Aculeata represents an evolutionary innovation—the transformation of a simple ovipositor (egg-laying tube) into a venomous weapon, which is why wasps, bees, and ants are all lumped together scientifically.
