A yellow and black transverse stripe is present between the first and second abdominal segments. It is concealed between the folds of the segments when the caterpillar is at rest. [24] [29] The abdomen is spotted transversely with light blue. Before pupating, the caterpillar will turn dark brown. It will reach a length of 5.5 centimetres (2.2 in).
The giant leopard moth (Hypercompe scribonia) is a moth of the family Erebidae.They are distributed through North America from southern Ontario, and southern and eastern United States through New England, Mexico, and south to Colombia.
Some caterpillars, like early instars of the tomato hornworm and tobacco hornworm, have long "whip-like" organs attached to the ends of their body. The caterpillar wiggles these organs to frighten away flies and predatory wasps. [18] Some caterpillars can evade predators by using a silk line and dropping off from branches when disturbed.
Young caterpillars are black with lighter colored transverse stripes. Older larvae have two color forms. The more common form is green with yellow and white transverse stripes; the rarer form is black and banded with white and orange. In both forms, between the swollen thorax and the abdomen, there is a yellow, black, and bluish-white band.
The larvae are black with orange spots arranged in lines down the whole body. Their head's prothoracic shield, and the anal plate, are one color, either green or orange with small black dots. [3] A tail-like spine protruding from the back of the body is a typical for sphingid moth caterpillars, known as “hornworms”. [2]
Trichodezia albovittata, the white-striped black moth, is a moth in the family Geometridae. It is found from Alaska to Newfoundland and Labrador, south in the east to North Carolina and in the west to northern California. [3] The wingspan is 20–25 mm. Adults are on wing from April to September. The larvae feed on Impatiens species.
The caterpillars are black, dark brown, or gray, with broad blue longitudinal stripes and thin yellow stripes extending along each side. The back of each abdominal segment bears a white spot that is wider toward the head end. The sides are partially covered with fur-like long setae. [2]
Papilio polyxenes, the (eastern) black swallowtail, American swallowtail or parsnip swallowtail, [4] is a butterfly found throughout much of North America. An extremely similar-appearing species, Papilio joanae , occurs in the Ozark Mountains region, but it appears to be closely related to Papilio machaon , rather than P. polyxenes .
