The adult moth is covered in long fur in colors ranging from dull orange to lemon yellow, with hairy legs and fuzzy black feet. [ citation needed ] The cocoons that these caterpillars emerge from vary in size from 1.3 to 2.0 centimeters and contain small hair pockets on the back and flattened front end, the latter covering the operculum at ...
Caterpillar (top view) The larva, a caterpillar, is completely covered in long, hairlike setae arranged in spreading tufts. Most are white, but there are black tufts along the middle of the back, and four long black hair pencils, two near the front, and two near the back. There are black spots along the sides, and the head capsule is black.
These toxic species, such as the cinnabar moth (Tyria jacobaeae) and monarch (Danaus plexippus) caterpillars, usually advertise themselves with the danger colors of red, yellow and black, often in bright stripes (see aposematism). Any predator that attempts to eat a caterpillar with an aggressive defense mechanism will learn and avoid future ...
Caterpillars are brown or reddish-brown and very hairy, with bundles of black and yellow hairs along the back. The hairs on caterpillars and pupae can irritate human skin. Adult moths have reddish-brown wings with silvery spots. [3]
Caterpillars of many species can cause irritation by their hollow body hairs that envenom or detach easily, or can be poisonous if ingested. [5] Prior to investigations into Lonomia caterpillars, it was not known that caterpillars could produce toxins in sufficient quantities to kill a human.
The young caterpillar is densely covered with yellow setae. The older caterpillar's setae are either pale yellow or white. All instars have thin, black setae on the first and third abdominal segments. On the eighth abdominal segment, there is one tuft of black setae. The caterpillar will reach a length of 50 mm (2.0 in).

Many species have "hairy" caterpillars that are popularly known as woolly bears or woolly worms. The scientific name Arctiinae refers to this hairiness (Gk. αρκτος = a bear). Some species within the Arctiinae have the word "tussock"' in their common names because they have been misidentified as members of the Lymantriinae subfamily based ...
The larva, known as the salt marsh caterpillar, which grows to about 5 cm (2 in) in length, is highly variable in color, ranging from pale yellow to rusty orange brown to dark brownish black. It is hairy, with numerous soft setae, growing in tufts (several tufts on each segment), with a few individual hairs that are longer toward the end of the ...
