Belanger JH, and BA Trimmer (2000) Kinematic and electromyographic analyses of proleg function during crawling in Manduca sexta.
We have combined kinematic and EMG analysis of proleg movements during crawling to examine the roles of these muscles during normal behavior.
In crawling animals, the reflex in a given proleg was suppressed during stance of that proleg.

These Crochets are arranged in a circle, when the proleg is lowered the hooks of the crochets swing down and out and hook into the silk mat or attach to a leaf.
The larva's wavelike motion is due to the lowering and raising of its prolegs.
On the underside of the abdomen are a number of prolegs that ar equipped with thousands of tiny hooks that help the larva walk.

 EEBWEB - EEB Drift for: (date)   (Site not responding. Last check: 2007-10-10)
During this period, ecdysteroids (molting hormones) trigger dendritic regression in proleg retractor motoneurons and the weakening of monosynaptic excitatory inputs to the motoneurons from proleg sensory neurons.
During the pupal stage, some proleg muscles and motoneurons are respecified for a new role in the circulatory system.
The synapses from proleg sensory neurons to proleg retractor motoneurons show multiple forms of activity-dependent plasticity yet the strength of these synapses remains stable during neural correlates of PWR habituation.

 Physiological Action of Octopamine and Nitric Oxide Metabolites

Righting ability is characterized by the time it takes the larva to roll upright with all prolegs on the surface after placed on its side.
Proleg withdrawal response is characterized by the percent of the larva's prolegs that respond to a sharp stimulus.

Cell culture of mechanoreceptor neurons innervating proleg sensory hairs in Manduca sexta larvae, and co-culture with target motoneurons.
The tip of each proleg in Manduca sexta larvae bears a dense array of mechanosensory hairs termed planta hairs (PHs), each innervated by a single sensory neuron (termed a PH-SN) located in the underlying epidermis.
These synapses mediate a proleg withdrawal reflex, exhibit multiple forms of activity-dependent plasticity and weaken during the prepupal peak of ecdysteroids.

Then, further along the body you can see four "prolegs" gripping the stalk of the plant (a fifth proleg grips the plant at the very rear of the animal's abdomen).
It wasn't until we got back home when I cropped the photographs and decided which to keep and which to discard that I noticed a very slight difference in these two photos.
While I cannot be certain of this, I think that tiny object may be a parasitic wasp caught in the act of injecting an egg into the caterpillar.
