The popular and furry Eastern Tent Caterpillar Moth picks the perfect tree to start a family where the offspring make a mess of things.
The Eastern Tent Caterpillar Moth gets its name based on the behavior of its caterpillars. Together, a cluster of young caterpillars create a "tent" from their silk and use it as a home on the tree or shrub they are feeding off. The yellow and black, meal worm-like caterpillars come and go during the day as they eat, returning at night for protection from the elements and potential predators. The tents are sticky and difficult to remove from branches. Because of feeding activity, dead leaves and fruit get trapped inside, creating unsightly branches.
Adult moths have brown hair all over them. Two thin, but obvious white lines cross their forewings at the center and lower portion. Brown antennae are comb-like and large. The thorax is covered in dense brown hairs. Like most moths, Eastern Tent Caterpillar Moths are attracted to lights at night and are nocturnal. They are commonly seen around roses and fruit trees, like apple, cherry and peach, where they are likely to lay their eggs. Female moths lay black egg sacs on twigs, near a leaf bud so the young caterpillars can eat the new leaves immediately after they hatch. Because the caterpillars feed off of trees that bear fruit that humans eat, they can considered pests.
Scientific Name: Malacosoma americanum
Butterfly or Moth
Size (Adult; Length): 30mm to 41mm (1.17in to 1.60in)
Note: An insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Butterfly and Moth Anatomy
Antennae: Butterflies and Moths have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and proboscis.
Thorax: Home to the three pairs of legs as well as vital internal organs.
Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.
Forewing: The upper, forward wing pair used for flying.
Hindwing: The lower, rearward wing pair used for flying.
NOTE: Butterflies and Moths are part of the Lepidopteran order as they share many similarities.
