- adj. the larva of any geometrid moth. They are so called because they move by a process in which they first pull the rear legs forward toward their front legs, forming a loop which resembles the process of measuring with a tape measure. The motion is completed by subsequently moving the front legs forward to an advanced position. See Geometrid.
