ABSTRACT Insect legs serve as crucial organs for locomotion and also act sensory probes into the environment. They are involved in several complex movements including walking, jumping, prey capture, manipulation of objects, self‐grooming. These behaviors require continuous modulation motor output through mechanosensory feedback, which is provided by numerous mechanosensors located on cuticle within soft tissue. A key organ insect leg, femoral chordotonal (FeCO), detects femoro‐tibial joint. This multifunctional senses both self‐generated (proprioception) external stimuli (exteroception). Movements tibia alter length FeCO, activates embedded neurons. Due to mechanical nature these stimuli, structure material properties FeCO their function, alongside encoding Here, a first step toward understanding how its modulates we characterized morphology anatomy hawkmoth Daphnis nerii .
