Inchworm. A caterpillar of the family Geometridae (inchworms or measuring worms) walking up a plant stalk. The family is so named (geometer = one who measures the Earth) because of the characteristic movement of the caterpillar, which, having only two pairs of limbs on its abdomen, drags itself along by stretching the front of its body forward, taking hold with the thoracic feet, and looping the rear portion of the body up to meet the front parts. With around 4000 species, the geometers form one of the largest families of the butterflies and moths.
