Hi Sorie, i believe these are both white-lined sphynx moth caterpillars. They are known for enjoying 4 o'clocks. They are related to the tobacco hornworms which are super common on tomato plants around here (anything in the nightshade family too). They are beautiful moths if you can afford to share your plants with a few, but they can eat quite a bit so a lot of people dispatch them. Hope that helps!
