I don’t think I’ve seen a bug this big in New York before. It’s slowly walking around my sidewalk and sticking its butt up in the air like this, with a yellow thing that is protruding and retracting.

Hi J,
Your insect is a female Broad-Necked Root Borer, Prionus laticollis, and the yellow thing is her ovipositor which is used to lay eggs. According to BugGuide: “Eggs are inserted into ground (or under litter) in groups. Larvae tunnel downward to feed on living roots of a variety of trees and shrubs. At first they may feed on bark, but then proceed to hollow out small roots.”
