Craesus latitarsus, Dusky Birch Sawfly, larvae
© John Pickering, 2004-2014

Dusky Birch Sawfly larvae feed gregariously together, consuming one leaf and then the next. They may keep their tails away from the leaf as a means of waste management. If their frass lands on their leaf, they are more likely to spread pathogens to each other.
