That is a VERY good question. I was just researching the exact thing. While there are almost 300 species of MOTH caterpillars that will, at least ocassionally, eat maple leaves (Eastern US only--I can't say anything about the rest of the world) based on information from the "Bringing Nature Home" website, there are NO LISTINGS at all for ANY butterfly caterpillars in "Caterpillars of Eastern North America" by David Wagner, nor have I found any internect references contradicting this conclusion. One comment though, there are photographs of the Harvester Butterfly, North Americas only carnivorous caterpillar, eating Wolly Maple Aphids and these aphids are only found on maple trees!
