Inchworm

name for the larvae of moths of the family Geometridae, a large, cosmopolitan group with over 1,200 species indigenous to North America.
I peered closer and realized that there was some sort of inchworm moving along the stem. I took a few pictures and headed to bugguide.net to do some research.
It is one of the Emerald Moth Caterpillars (synchlora sp.).
To move, they grasp first with those front legs and then with their back legs, in inchworm fashion. They swim by rapidly bending and straightening their bodies.
To grow, skeleton shrimp shed their old exoskeletons and form new, larger ones.
Rectilinear: Large, heavy snakes also use caterpillar or "inchworm" movement to travel in a straight line. They are able to move the skin of the belly forward and then pull the rest of the body along.
They move with a concertina or "inchworm" motion.
Juvenile snakes are brick-red or dull orange and turn emerald green over a 12 month period.
It explores the body in its inchworm style until it finds its choice site for a meal, for instance, at the toes or along the shin. It quickly perforates the skin and begins to feed.
What They Do
Constant movement and soft, dense fur keep otters warm in Minnesota winters. When traveling on land, otters move along by flexing their spines inchworm-style. Always on the move, they may travel as far as 25 miles in a single week.
In response to disturbances by an approaching host, the leech will commence "inchworm crawling", continuing in a trial and error way until the anterior sucker touches the host and attaches.
