Question: what is the difference between gypsy moth caterpillars and tent caterpillars?
Answer: The eastern tent caterpillar has a diagnostic solid white stripe down the back, while the forest tent caterpillar has a series of keyhole-shaped spots. The gypsy moth caterpillars are also hairy, but lack the white stripe down the back or the series of keyhole-shaped spots found on the tent caterpillars.
