"The Geometrina in the larval condition have only four prolegs, the usual number being ten, and in moving these are brought close up to the last pair of thoracic limbs, thus giving the caterpillar a looped appearance, hence the term "loopers" usually applied to these moths; they then hold on by the prolegs, and releasing those in front carry the body forward until the arched appearance is gone. They thus move by an alternate process of looping and straightening their bodies. The larva of Geometers have also the curious havit of fixing themselves by their hind feet to the branch of a shrub, throwing the remainder of their bodies out, and remaining motionless in this position for hours, thus exhibiting an enormous amount of muscular energy." &mdash; Encyclopedia Britanica; 1893
