There is no easy way to tell them apart without identifying the caterpillar to family or species. As a general rule, very few butterfly caterpillars are fuzzy or hairy, so furry caterpillars are most likely moths. Also, in the US, if the caterpillar is more than 2 inches long, it must be a moth larva. However, there are thousands of moth caterpillars and hundreds of butterfly caterpillars that could be described as "spiny" or "smooth". These come in all colors imaginable, and many different patterns. There are both moth and butterfly caterpillars that are black, green, red, orange, white, and other colors, and they may be smooth or spiny. Only by looking up what particular species matches your caterpillar's description will you know what it will turn into.
