Called an ovipositor, this egg - laying structure is often longer than the body. It is no thicker than a horsehair and has three threadlike strands that slide back and forth to force the egg down the tube.
Dējeklim, kas nav resnāks par zirga astru, ir trīs pavedieni, un, slidinādama šos pavedienus šurpu turpu, jātnieciņu mātīte virza oliņu lejup pa dējekli.
