Green wiki:
>For other uses, see Green (disambiguation). Green is a color seen commonly in nature. Many plants are green mainly because of a complex chemical known as chlorophyll which is involved in photosynthesis.Green light has a wavelength of roughly 520â570 nm and is one of the additive primary colors. It is the complement of magenta. Many artists, however, continue to use a traditional color theory in which the complement of green is considered to be red.People who are red-green color blind can often distinguish between the two colors but confuse them with other colors, for example, bright green with yellow; dark green with brown.

Caterpillar wiki:
>This article is about insect larvae. For the company, see Caterpillar Inc.; for the vehicle locomotion systems, see caterpillar track (land) or caterpillar drive (water). A caterpillar is the larval form of a lepidopteran (a member of the insect order comprising butterflies and moths). Caterpillars have long segmented bodies and many sets of "legs". They eat leaves voraciously, grow rapidly, shed their skins generally four or five times, and eventually pupate into an adult form.
