你可知道 ？

The name sawfly comes from the saw-like appearance of the ovipositor, which is what females use to cut into the plants and lay their eggs in them. Horntails are a special kind of wood-eating sawfly and their name comes from having a stout that is used to pierce through the bark and lay their eggs inside the wood.
