3. The female wasp has an ovipositor twice as long as its body.
Biology and ecology
1. A female parasitoid inserts its long ovipositor inside the stem borer larva to lay a single egg. Each larval host allows development of a single larval parasitoid.
Stenobracon nicevillei is found in dryland environments
