caterpillars

  • Caterpillars can be difficult to identify because they go through 5 stages of growth. Each stage is called an "instar." As a caterpillar grows, it "molts" 5 times before it becomes a chrysalis.

  • Orgyia leucostigma, the white-marked tussock moth, is a moth in the family Erebidae. The species was first described by James Edward Smith in 1797. The caterpillar is very common especially in late summer in eastern North America, extending as far west as Texas, California, and Alberta.

  • The forest tent caterpillar moth (Malacosoma disstria) is found throughout North America, especially in the eastern regions. Unlike related tent caterpillar species, the larvae of forest tent caterpillars do not make tents, but rather, weave a silky sheet where they lie together during molting. They also lay down strands of silk as they move over branches and travel as groups along these pheromone-containing silk trails. The caterpillars are social, traveling together to feed and massing as a group at rest. Group behavior diminishes as the caterpillars increase in size, so that by the fifth instar (molt) the caterpillars are feeding and resting independently.
  • The fall armyworm (Spodoptera frugiperda) is a species in the order Lepidoptera and is the larval life stage of a fall armyworm moth. The term "armyworm" can refer to several species, often describing the large-scale invasive behavior of the species' larval stage. It is regarded as a pest and can damage and destroy a wide variety of crops, which causes large economic damage.

  • Euchaetes egle, the milkweed tiger moth or milkweed tussock moth, is a moth in the family Erebidae and the tribe Arctiini, the tiger moths. The species was first described by Dru Drury in 1773.
