In most insects, the femur is the largest region of the leg; it is especially conspicuous in many insects with saltatorial legs because the typical leaping mechanism is to straighten the joint between the femur and the tibia, and the femur contains the necessary massive bipennate musculature.
Legs of insects (adults and larvae) are jointed and have five parts: coxa, trochanter, femur, tibia, and tarsus. The plurals of these words are coxae, trochanters, femora, tibiae, and tarsi. The tarsus is the part farthest from the insect's body, and it ends typically in a claw or pair of claws.
BASIC STRUCTURE OF THE LEGS. Each leg consists typically of six segments, articulating with each other by mono-or di-condylic articulations set in a membrane, the corium. The six basic segments are coxa, trochanter, femur, tibia, tarsus and pretarsus (Fig. 8.1a).
Insects are arthropods that have a body covered with a chitinous cuticle, divided into a head, a thorax and an abdomen, 3 pairs of segmented legs, one pair of antennae and (in most cases) wings. The structure of insects depends on the environment, lifestyle, type and manner of feeding.
3 dni temu · Insect leg diagram. There are five parts to an insect leg: Coxa: point of contact with the thorax; Trochanter: a joint-like structure connecting the femur and coxa; Femur: typically the largest and most powerful region of the insect legs.
Insects have six segmented legs, which take many different forms depending on their function. For example, legs might be modified for swimming, jumping, capturing prey, or holding on to a mate. Most insects have four wings, but some insects have none.
Most insects have three pairs of walking legs — one pair on each thoracic segment. Each leg contains five structural components (segments) that articulate with one another by means of hinge joints: Coxa. Trochanter. Femur. Tibia. Tarsus.
