Fun Eastern Tent Caterpillars Facts For Kids
Gallery
The biological genus Malacosoma, categorized under the family Lasiocampidae, is known to encompass about 26 different species of moderately sized moth larvae or caterpillars known as tent caterpillars. These tent caterpillars are particularly known for their large silk tents.
Faithful to their infamous social behavior, the members of Malacosoma americanum work in cooperation with the other members of their species immediately after emerging from their eggs, in order to build their tents.
The tents of these moths on the host plant serve as shelter, in protection from predators and dwelling for their sleep cycles during the night.
The eastern tent caterpillar (Malacosoma americanum) is known to show parasitic behavior during the late spring days by foraging on leaves of different hosts. However, these pests do not cause any long-lasting damages, as long as the infestation of this pest fall webworm is not on a large scale.
The favored host trees for these caterpillars are apple trees and cherry trees. Here are some of the most important facts about the eastern tent caterpillar. For more relatable content, check out these eastern Hercules beetle facts and stink bug facts for kids.
Eastern Tent Caterpillar Interesting Facts

Where does an eastern tent caterpillar live?
The tent caterpillar (Malacosoma americanum (Fabricius)) can be located along the eastern and central stretch of the United States like the fall webworm. Additionally, these pests can also be traced along the western Rocky Mountains. Their host plants include apple trees and cherry trees.
What is an eastern tent caterpillar's habitat?
The prime habitation of eastern tent caterpillars includes forests with fruit trees where these pests build tents (largest among the tent caterpillar species). The eastern tent caterpillar is also found near human habitations particularly during the late spring or early summer days, much like the fall webworm.
The common plant species used by these caterpillars for nesting include forest trees and deciduous shade trees like maple, peach, cherry, and willow.
Who do eastern tent caterpillars live with?
Eastern tent caterpillars are found in groups known as cohorts which include as many as 50-200 individuals. These pests lay their eggs on the thin branches of cherry trees or on the branches of apple trees and the eggs will hatch in the early weeks of April.
How long does an eastern tent caterpillar live?
The total life cycle of Malacosoma americanum is about 10 months. Wherein the adult males are known to survive for a week or more, however, in contrast to this the females Malacosoma americanum breathe their last soon after laying eggs, much like the fall webworm insect.
How do they reproduce?
During the breeding season, the male eastern tent caterpillar intently seeks out females for copulation. In fact, the competition for breeding is quite high amongst the male members, which in general are in higher ratios in comparison to the female counterparts (in most tent caterpillar populations).
After selecting potential partners short copulation is followed resulting in the fertilization of gametes. Following fertilization, females lay about 150-400 eggs in protected areas in the form of tent caterpillar egg masses in loosely woven webs.
Eastern tent caterpillar egg masses do not encompass foliage. The female eastern tent caterpillars die soon after laying the eggs.
What is their conservation status?
The conservation status of the eastern tent caterpillar as of now is Not Evaluated by IUCN. These insects are present in abundance on a malus tree and a prunus tree in their natural habitat.
Eastern Tent Caterpillar Fun Facts

The members of the eastern tent caterpillar are gregarious in nature, that is this pest is found in close proximity forming groups with their siblings which may include as many as 200 individuals.
The toxins released by eastern tent caterpillars are known to induce abortion in horses when this insect is ingested by the grazing mare.

This pest builds tents, in fact, the largest among the tent caterpillar species and hence draw their name eastern tent caterpillar. You can safely touch these caterpillars as they pose no risk to humans on touching as there is no risk of any venom being transferred to humans by these pests.
