The proprioceptive function of a campaniform sensillum is to perceive stresses and changing forces on the cuticle, facilitating insect locomotion including walking and flight. In the aphid genus Mindarus (Hemiptera: Aphididae), campaniform sensilla are often clustered in groups and are found at specific locations on the insect's appendages. Ring-shaped, approximately 5µm in diameter, these sensilla are found in predictable numbers on the pedicel (1), the trochanter (4), the femur (2-4), and the distitarsus (1). Those situated on the wings are variable in number and size. The wing sensilla form five identifiable groups: four on the forewing and one on the hindwing, with an average of 4 or 6 sensilla per group. Light and electron scanning microscopy was conducted to reveal their external anatomical detail. The pattern and distribution of campaniform sensilla does not appear to inform Mindarus taxonomy.
