I ran a search for black vine weevil larvae and all I could find was one
infested with nematodes. As near as I could tell it was whitish with a
dark head, but there was no mention of hairiness on the larvae. The adults
have black hairs, but they're nipping the leaves, not roots. The iris
borer is a different color (pinkish, as I recall), but I couldn't get a
size comparison between black vine weevil larvae and iris borers. I didn't
look into the swift moth larva -- I don't want to know about fast bugs.
