Information About Eastern Tent Caterpillars

Eastern tent caterpillars are a specific species of the tent caterpillars that are generally of a number of species and subspecies.

The Eastern tent caterpillars happen to be one of the most prominent species of the tent caterpillars. They are scientifically known as Malacosoma Americanum. You may be amazed to know that the Eastern tent caterpillars have been found to be social as well as univoltine species. It has been found that the Eastern tent caterpillars are capable of building or forming communal nest on the tree branches.

The Eastern tent caterpillars mostly inhabit cherry orchards, crabapple and apple. However, these can also be found in plum trees, pear, peach, maple and hawthorn trees. Sometimes they are confused with the gypsy moth that they are not in reality. They are also sometimes mistaken as fall webworm. What is even more extraordinary, the Eastern tent caterpillars are very often referred to as the bagworms. This reference seems to be quite amazing since bagworm happens to be a very common name that is applied in order to refer to the caterpillars that belong to the family of the Psychidae. The bagworms are, in no way considered to be related with the Eastern tent caterpillars.

In terms of interaction complexities, the Eastern tent caterpillars occupy the pinnacle of sociality when it comes to taking about caterpillars. The adult moths lay between 200 and 300 eggs in a single batch during late springtime or early summer months. But the small caterpillars quiesantly lie in the eggs, gradually chewing their way out the eggshells. This procedure lasts for year until the next spring approaches. The new hatchlings waste no time and start building their silken tents soon enough. They increase in size by the day and they weave their tents accordingly to accommodate themselves.

The tents build by the Eastern tent caterpillars are certainly one of the largest build by any caterpillar and have been found to have a layered structure. It is because of this layered structure of the tents that they prove to be thermally heterogeneous. The Eastern tent caterpillars are, therefore, capable of making necessary adjustments to the external temperature by moving from one layer to the other. The Eastern tent caterpillars have also been found to aggregate on the outer porting of the shaded side of their tents in order that cooling and convective heat loss can be enhanced.

The Eastern tent caterpillars are endowed with the ability to generate little amount of metabolic heat while digesting their meals. The amazing fact is that if the Eastern tent caterpillars gather all together after they have fed themselves, the heat of the mass reaches even several degrees. Wherever the Eastern tent caterpillars go, they keep secreting silk from a spinneret. When the Eastern tent caterpillars move on different parts of the trees, they tend to confine their movements within the trails. One more interesting fact about the Eastern tent caterpillars is that they are very important as a plant pest since it generally defoliates the ornamental trees.
