Inch worm

They have no legs on their abdomen Inchworms have three pairs of true legs at the front end but only two or three pairs at the rear. The inchworm moves by drawing its back end forward while holding on with the front then moves the front section forward while holding on with the back. A handful of other insects are known to prey on inchworms, the most dangerous of which are wasps. A female wasp will often lay its eggs inside an inchworm's eggs, allowing the wasp larvae to become parasites.
