Description
Fun Facts:.....he Eastern Tent Caterpillar is the most social of the Missouri caterpillars. Typically they move out to feed three times a day- before dawn, mid-afternoon and after sunset. They leave a pheromone trail between the feeding site and the tent. When a caterpillar discovers a particularly good site, it leaves a stronger trail, sometimes recruiting the whole colony.Although they would appear to be sitting ducks for predators, they have their defenses. When attacked by a parasitic insect attempting to lay its eggs on a caterpillar, it starts thrashing about, followed rapidly by the whole colony, creating a confusing target. Caterpillars feeding on cherry leaves acquire cyanide from them which they can regurgitate on predators. Needless to say, few birds (except for the cuckoo) acquire a taste for them.Perhaps the most amazing thing about them is their construction skills. They daily crawl over the tent surface, laying down silk as they go. As the silk dries, it shortens and pulls away from the underlying layer, creating a space. A large tent is made up of multiple concentric layers which they can enter. They are able to control their temperature this way. A colony huddled together in the center of the web during a freeze emits metabolic heat and can maintain a temperature of 70-80 F. The last of the six instars leaves its siblings to develop a cocoon on the ground. The moth that emerges is ordinary. Its only claim to fame is a faint resemblance to a gypsy moth.Most of the trees which are denuded of leaves will leaf out again in a few weeks with no permanent harm. For that reason, I could easily let all of them alone to complete my life cycle, except for one thing. My wife will still rip down their tent with her accustomed violence.
