Could you please tell me what the insect in the attached image is. We have now found two, both on the balcony. Somehow they are getting through the fly screens. They seem to have a very hard carapace(?) and were extremely difficult to kill. We didn't want to touch them just in case they had a sting. To possibly help with identification, we are located in Wuzhishan, a town in the centre of Hainan island in China. It's almost rainforest climate and our apartment backs on to a rive. With thanks in advance - Bob


Thank you for including the images with your question.

These *are* wasps, called "ensign wasps," but they do not sting.  You will want to keep them around after reading this:


So, no worries.

I answer insect and spider identification questions ONLY. Attach images if possible. No "what bit me?", "what do I feed this bug in captivity?", or science fair project questions please. NO TECHNICAL QUESTIONS ABOUT INSECT PHYSIOLOGY.
