Can someone please identify these caterpillars. They are infesting one of my plants 🙁
Knowing the plant host is often a great help in identifying caterpillars and other herbivorous insects. This is a Spotted Oleander Caterpillar, Empyreuma affinis, and it is commonly found feeding on oleander. According to Featured Creatures: “It is a native of the Caribbean region and has been recorded from Guadeloupe, Martinique, Haiti, Dominican Republic, and Cuba.” The plant in your image does not appear to be oleander, which is the food plant identified on BugGuide. You can compare your image to this image on BugGuide for verification.
