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.
[13]: 644 Caterpillars of many taxa that have sequestered toxic chemicals from host plants or have sharp urticating hair or spines, display aposematic colouration and markings. [66] Caterpillars undergo ecdysis and have a number of larval instars, usually five but varying between species. The new cuticle is soft and allows the increase in size ...
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.
As the larvae develop, they will lose their orange color and will turn bright green and urticating, having many spines. 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 resting, the caterpillar usually holds its legs off the surface and tucks its head underneath (praying position), which, resembling the Great Sphinx of Giza, gives rise to the name "sphinx moth". [5] Some tropical larvae are thought to mimic snakes.
PDF version of the chart. The colors of the chart were described by McCamy et al. with colorimetric measurements using the CIE 1931 2° standard observer and Illuminant C, and also in terms of the Munsell color system. Using measured reflectance spectra, it is possible to derive CIELAB coordinates for Illuminants D 65 and D 50 and coordinates ...
