Looked like it might be dead, laying in hot sun and was unresponsive. I placed it on damp paper towel in the shade to see if it would revive. Showed signs of getting better. It might have become food for something else. Spotted another one sunk in a lake. It looked like a dill pickle 🥒!! They didn't thrive in the 36 degree heat.
Found on road. Noticed two black aphids on its back. Also parasitic eggs(?) near its head.
