The first instar: Caterpillar larvae vary in size and are capable of being between 1.5-2.0mm in length. [3] At this stage a hatchling lacks its characteristic coloring and instead tends to be a translucent lime green with green or black tentacles and green protuberances along the skirt which lack the long spiny thorns that are seen in older ...
When the eggs hatch, small yellow caterpillars emerge. As the caterpillars age, they molt five times (the fifth being into a pupa). Each instar is slightly different, but on their fifth and final instar, they become bright green with silver spots on their sides. They feed heavily on their host plant and can grow up to 3–4 inches long.
The green caterpillars have two lateral stripes, the upper one being bright red and the lower one being white. These caterpillars can reach sizes of 7 cm in length. [20] When the caterpillars are ready, they spin a flimsy, valveless cocoon made from a dark, coarse silk.
Described and named Phalena plumata caudata by James Petiver in 1700, this was the first North American saturniid to be reported in the insect literature. [2] The initial Latin name, which roughly translates to "brilliant, feather tail", [9] was replaced when Carl Linnaeus described the species in 1758 in the tenth edition of Systema Naturae, and renamed it Phalaena luna, later Actias luna ...
Megalopyge opercularis is a moth of the family Megalopygidae.It has numerous common names, including southern flannel moth for its adult form, and puss caterpillar, asp, Italian asp, fire caterpillar, woolly slug, opossum bug, [3] puss moth, tree asp, or asp caterpillar.
The caterpillars grow to about 25 mm long. In color, they vary from light green to a dark brownish green. Light green caterpillars have white lines running down the body from the head to the tip of the abdomen while the darker caterpillars have a black stripe the length of their back.
As caterpillars, they have a wide range of color phenotypes but show consistent adult coloration. [3] With a wide geographic range throughout Central and North America, H. lineata is known to feed on many different host plants as caterpillars and pollinate a variety of flowers as adults. [4] [5]
As the caterpillars grow larger into the second larval instar, they become yellow green. During the third, fourth, and fifth instars, the cecropia moth becomes rather large and bluish green. At these final stages, the tubercles become blue, yellow or orange, depending on location on the body, while the black hairs are eventually lost.
