Females appear to have two menacing stingers, but one is actually an ovipositor. The thick ovipositor is a tube used to directly inject eggs into tree trunks and other durable wood where they are less likely to found and eaten by other insects. That sturdy spine aids in splitting the wood before the eggs are laid.

Larvae hatch inside the wood and tunnel through it, emerging as adults. Adults drink nectar and water. Both genders of Horntail Wasp species have spines at the tip of their abdomen.
