Tent caterpillars are sociable and community-spirited. The work cooperatively to gather food:
Studies have shown that eastern tent caterpillars recruit their tent mates to go on food finds. Caterpillars move from the tent in search of food, laying down an exploratory pheromone trail as they pass over the branches of the host tree. These chemical exploratory trails allow caterpillars to find their way back to the tent. If a caterpillar finds food and feeds to repletion, it returns to the tent, laying down a recruitment trail that serves to recruit hungry tent mates to its food find.These caterpillars present no serious risk to the tree. They should be welcomed as exemplary Rosslyn residents.
