No sign of anything eating dead Japanese beetles here - I wish. Perhaps because of the smell. Once dead (especially in numbers, as when I dump the traps) those beetles really stink! Once all the beetles were dead, I would dump them in one location in the gravel driveway, hoping something (skunk, possum, raccoon) would develop a taste for them. Not only did that not happen, but in Spring all of the beetles from the previous year were still there, like metallic mini-mummies.it takes quite a long time for those beetles to actually drown. i'd made the mistake one summer of throwing them at the end of the driveway to encourage birds to learn to eat them only to finally figure out that they were just crawling away. once i realized that i started squishing them with my fingers or stepping on them and leaving them in the gardens hoping to accomplish the same. something was eating them. i don't know what but i suspect that it could have been chipmunks. no proof, i still don't know for sure what is going on out there. birds would be the other suspect, but until i verify it i can't say for sure.
and no, i'd not try to hand pick flea beetles... i'm crazy, but i do have my limits.
