Solution(By Examveda Team)

The highly evolved insect order is Hymenoptera.
Hymenoptera is a large order of insects, comprising the sawflies, wasps, bees, and ants. The name Hymenoptera refers to the wings of the insects, but the original derivation is ambiguous.
In the more ancestral hymenopterans, the ovipositor is blade-like and has evolved for slicing plant tissues. In some species, the ovipositor has become modified as a stinger, and the eggs are laid from the base of the structure, rather than from the tip, which is used only to inject venom.
