Fascination with Horntail Wasps
This article was published originally on 7/27/2011
I am always fascinated by insects that can drill through bark to lay their eggs. One such insect is a horntail wasp. I was lucky enough to catch a female in action a few weeks ago. You can see in the photo her ovipositor (a fancy term for egg depositor) is firmly sticking into the bark under her body. This is not a quick process as she inserts here ovipositor up to ¾ of an inch into the wood before laying an egg. Along with the egg she also introduces a symbiotic fungus that is necessary for larval survival.
