How many legs do monarchs have?

It sometimes looks like adult monarchs only have 4 legs, and that caterpillars have a lot more. However, all insects, including monarchs actually have 6 legs. Adult monarchs hold their front two legs close up to their bodies most of the time, and can even use these two front legs to taste-test milkweed before laying eggs on it! Monarch caterpillars have have 6 true legs (3 sets) and 10 prolegs or false legs (5 sets).
