Hi all! I found this scary-looking insect on a rock in a park near my house. The rock was otherwise covered with box elder bugs (both adults and immatures), and then there was this guy. I know next to nothing about insect identification, so hopefully the picture will be useful for you all. Is that a stinger? Ovipositor? From my brief searches, I want to put it in the hymenoptera order, but I can't seem to get any more specific. Do you have any clues?
