What's the difference between caterpillar and proleg?
Caterpillar
Definition:
(n.) The larval state of a butterfly or any lepidopterous insect; sometimes, but less commonly, the larval state of other insects, as the sawflies, which are also called false caterpillars. The true caterpillars have three pairs of true legs, and several pairs of abdominal fleshy legs (prolegs) armed with hooks. Some are hairy, others naked. They usually feed on leaves, fruit, and succulent vegetables, being often very destructive, Many of them are popularly called worms, as the cutworm, cankerworm, army worm, cotton worm, silkworm.
(n.) A plant of the genus Scorpiurus, with pods resembling caterpillars.

(20) Two of the farms had army caterpillar (Mythimna convecta) infestations.
Proleg
Definition:
(n.) One of the fleshy legs found on the abdominal segments of the larvae of Lepidoptera, sawflies, and some other insects. Those of Lepidoptera have a circle of hooks. Called also proped, propleg, and falseleg.
Example Sentences:
(1) Other proleg motoneurons regress but do not die, indicating that dendritic regression is programmed separately from neuronal death.
(2) The principal locomotory appendages of the Manduca sexta caterpillar, the prolegs, are present on the third through sixth abdominal segments (anal prolegs located on the terminal segment were not included in this study).
(3) In this study we examined activity-dependent changes in the amplitude of the excitatory postsynaptic potentials (EPSPs) evoked in a proleg motoneuron by stimulation of individual planta hair sensory neurons.
(4) The larval-pupal transformation of the tobacco hornworm, Manduca sexta, involves the loss of many larval-specific behaviors, including a simple withdrawal reflex of the abdominal prolegs.
(5) At pupation the prolegs are lost, their muscles degenerate, and some of their motoneurons regress structurally.
(6) Two other differently fated abdominal muscles not associated with the proleg were also studied.
(7) In the present study we identified additional proleg motoneurons and their putative homologs in the non-proleg-bearing segments.

(9) The prolegs bear numerous mechanosensory bristle sensilla, each innervated by an afferent neuron that arborizes within the central nervous system (CNS).
(10) In the mosaic hemisegments, electrical stimulation of PH afferents evoked only a small synaptic depolarization of the proleg motoneurons, similar in amplitude to that recorded in normally developing pupae; thus, the developmental status of the afferents was irrelevant to the loss of the reflex.
(11) As a first step toward investigating the process of functional respecification at the synaptic level, we searched for larval interneurons that affected the activity of proleg motoneurons, and followed these interneurons into the pupal stage.
(12) Interneurons were judged to be individually identifiable based on their effects on proleg motoneuron activity and their anatomical features.
(13) The abdominal prolegs, which are the principal locomotory appendages of the caterpillar, are lost during the larval-pupal transformation.
(14) Cobalt-staining of the proleg MNs and planta hair afferents shows that the afferents terminate in ventral neuropil, and the proleg MNs have an unusual ventral projection into this region.
(15) Following adult emergence all but one of the respecified proleg motoneurons dies.
(16) We have followed the fates of a proleg retractor muscle, PPRM, and its single motoneuron, PPR.
