Looper Caterpillar

Description:

Walking thru a fruit farm near a tropical jungle, by a river stream and a caterpillar swinging in the air drops on my arm. Posing in the nice sunshine made the photo opt a great one.

Notes:

The name "Geometridae" ultimately derives from Latin geometra from Greek γεωμέτρης ("geometer, earth-measurer"). This refers to the means of locomotion of the larvae or caterpillars, which lack the prolegs of other Lepidopteran caterpillars in the middle portion of the body, with only two or three pairs at each end. Equipped with appendages at both ends of the body, a caterpillar will clasp with its front legs and draw up the hind end, then clasp with the hind end (prolegs) and reach out for a new front attachment - creating the impression that it is measuring its journey. The caterpillars are accordingly called loopers, spanworms, or inchworms after their characteristic looping gait. The cabbage looper is not an inchworm, but a caterpillar of a different family. 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 the prolegs, increasing the resemblance. Some have humps or filaments. They are seldom hairy or gregarious and are generally smooth. Typically they eat leaves. However, some eat lichen, flowers or pollen.
