Which part of an insect's leg connects the trochanter to the femur?

The patella is the structure that connects the trochanter to the femur in an insect’s leg. Insect legs are composed of several segments, each with distinct roles and features. The trochanter is the joint that connects the leg to the body, while the femur is typically the longest segment of the leg, functioning primarily in movement and support. The patella acts as a hinge between these two segments, allowing for flexibility and movement, which is crucial for the insect’s mobility. Understanding the anatomy of an insect's leg and how each part functions in relation to one another is essential for grasping the broader concepts of entomology and pest control strategies.
