The name Geometridae derives from Latin geometra (geometer, earth-measurer). This refers to the means of locomotion of the larvae or caterpillars, which lack the full complement of prolegs seen in other lepidopteran caterpillars, with only two or three pairs at the posterior end instead of the usual five pairs. Equipped with appendages at both ends of the body, a caterpillar clasps with its front legs and draws up the hind end, then clasps with the hind end (prolegs) and reaches out for a new front attachment - creating the impression that it measures its journey. The caterpillars are accordingly called "loopers", "spanworms", or "inchworms" after their characteristic looping gait. In many species of geometer moths, the inchworms are about 25 mm (1.0 in) long. They tend to be green, grey, or brownish and hide from predators by fading into the background or resembling twigs. Many inchworms, when disturbed, stand erect and motionless on their prolegs, increasing the resemblance. Some have humps or filaments, or cover themselves in plant material.
