PROLEGS Meaning and
Definition
-
Prolegs are specialized appendages found in the larvae of insects such as caterpillars. They are fleshy, unjointed, and usually located on the abdominal segments of the larval body. Unlike true legs, prolegs do not have joints or claws. They are unique to the larval stage and are absent in the adult form of the insect.
Prolegs serve as an important means of locomotion for larvae, enabling them to move and cling onto various surfaces. While each larva may have a specific number of prolegs, typically there are usually more than the six true legs found on the thorax of the insect. The additional prolegs increase the stability and grip of the larvae, allowing them to navigate complex terrains such as plants and other substrates.
Prolegs have a circular arrangement of tiny hooks known as crochets, located on the underside of each proleg. These crochets have a gripping function, aiding in the larva's ability to hold onto surfaces and prevent it from falling off or being dislodged easily. The presence of crochets differentiates prolegs from true legs, which do not possess such structures.
Overall, prolegs are an essential adaptation for the larval stage of insects, enabling them to move efficiently and securely through their environment.
