  • Both male and female wood wasp has no any noticeable difference in their parts. But female does have a structure called ovipositor. This ovipositor is just for laying eggs not for stinging, and due to this female wood wasp has an elongated body than the male.
  • Scientists are greatly impressed by their ovipositor and develop neurosurgical probe. That performs the same function. It has two valves that keep on oscillating. The new Scientist magazine prescribes their function opposite to rigid surgical probes. Hence, this will provide the safest route while doing the brain surgery.

2. Diet and food for the wood wasps: The larvae emerge into an adult wood wasp by chewing wood. In the early phases, they feed upon softer wood than the typical horntail goes for the harder or strong wood. The emerging wood wasp can make any substance their food for the complete nourishment and development. Due to the chewing habit, they make comparatively large holes on the interior surfaces or ground and make them look horrific and disastrous. The damage can occur anywhere the most common areas can be room tiles, hardwood floors, carpets, wallboard, etc.

3. Reproduction and life cycle of wood wasp: A female wood wasp prefers a dead or depleted tree for laying eggs through ovipositor which is drilled 3 to 4 inches into the wood. And start laying eggs. While laying an egg, the wood wasp also pours fungi through the abdominal area. And continue to lay an egg up to 200. Each time the period for hatching eggs differs from 3 to 4 weeks approximately. And then larvae channelize its way with fungus-predigested wood parallel having grain with it. Larvae possess a circular body with a whitish color having no legs at all. But there is a spine present in the last segment of their abdomen. This spine helps the young larvae to move ahead. Initially, the larvae will feed on the softer wood of the trees, which is under the bark. Then it goes to the sap for further feeding and nourishing.  There are five immature stages for larvae feeding.  They can end after a year, but on cooler climates, it takes up to five years for the completion of processes. The larvae convert into an intermediate stage that is pupa. After chewing wood about 3 to 4 inches, it finally becomes an adult wood wasp.
