Explanation of Names

English word is from Middle English legge, meaning leg (1), that apparently from Old Norse (Jardine calls this Icelandic) leggr, a leg, a hollow bone.

Identification

leg - one of the six chief organs of locomotion of an insect, arising from the segments of the thorax, and which are made up of four main portions, the coxa, femur, tibia, and tarsus. (The second segment, the trochanter, is very short.)

Diagrams showing parts of the insect and arachnid leg:

Some insect larvae, especially caterpillars, have fleshy prolegs, often in addition to six true legs. Photos/diagrams showing prolegs:

Remarks

According to Jardine, Thomas Say called the entire insect leg the tibia, but this usage is not current today.
