Aim

To study the structure of the insect cuticle and segmentation.

Specimen & Apparatus

  • Insect part (e.g. beetle leg, ant, or small fly)
  • Slide and coverslip
  • Water or glycerine (optional)
  • Compound microscope

Method

  1. Place the specimen or part on a slide.
  2. Add a drop of water or glycerine if required.
  3. Apply a coverslip carefully.
  4. Examine under low power to observe overall structure.
  5. Increase magnification to study surface detail.

Observations to Make

  • Segmentation of the cuticle.
  • Surface texture and patterning.
  • Presence of joints or articulation points.
  • Any fine structures such as hairs or spines.
