I know the summer is really busy, but I was at a friend’s farm, and we found this bug on a tree in her yard. If you touch the white thing protruding from its abdomen, it pulls it all the way back in. It didn’t seem aggressive, but then she found another one and when she put them in a jar together, they fought. Can you please tell me what kind of bug this is?

This is a female Broad Necked Root Borer, Prionus laticollis. The ovipositor protruding from the abdomen is used to lay eggs beneath the bark and the immature grubs feed on the wood.
