I live in town and was suprise to find these big insects in one of my dying tree's in front of the house. I've never seen these before but with some research I think they are Megarhyssa macrurus lunator. There is over 10 of theses all in the same tree. Are these usualy found in New-Brunswick and in the city? Also are these type of bees or wasp dangerous? Can they sting you? I have more pictures if you would like to see them. If you have any information can you email me at guygirouard@hotmail.com .. Thanks

There appear to be two different Megarhyssa species depicted in these images.

Hi
Really, these were all in the same tree at the same time, is this common and do you usualy see these in a populated area? I live right in town.

M. macrurus…
Not to worry. These large wasps are quite harmless and do not sting. They are quite common in forests throughout North America. I would suggest leaving at the species level unless you have some suggestive evidence to place at subspecies. If you have any close-ups, these would be welcome additions to the guide.

Hi
Yes, I have a few more that are close up, should I add them one by one on the ID Request or can I send these to you? Would the name of this species be Megarhyssa macrurus lunator?

You can just go to this image and click on "Add image" on the bottom of the screen to add additional images. If you are sure that this is Megarhyssa macrurus lunator, then a new guide page can be created for this subspecies. If their is some doubt, I would leave at the species level (Megarhyssa macrurus).

They're not male...
They're females. Laying eggs. The long thing is they're ovipositer.
