- Apical : the anterior corner of the wing
- Base/Basal area of wing : region close to the point of attachment to the thorax
- Cell : the central area surrounded by veins
- The cells are spaces formed by the crisscrossing of the veins. They can be "open" (extending to the margin of the wing) or "closed" (delimited only by veins). [Terminology]
- Costa or Costal area of wing : The leading edge of the wing
- Disc or Discal area of wing : The central band passing through the cell
- Dorsum : trailing edge of wing
- Eyespot or Occelli : spots resembling mammalian eyes. Can also be used to refer to simple eyes.
- Terminal and marginal spots
- Termen : the edge of the wing most distant from the body
- Tornus or Tornal area of wing : the posterior corner of the wing
- Vein : hollow structures formed from the coupling of the upper and lower walls of the wing. They provide both rigidity and flexiblility during flight. [More] [Terminology]

- Brand
- Cremaster : most butterfly pupae are attached to a surface by a silken pad spun by the caterpillar and a set of hooks (cremaster) at the tip of the pupal abdomen.
- Labial palpi or Palpi
- Osmeterium : fleshy structure on some larvae, often discharging odorous chemicals
- Spiracle : respiratory openings on the thorax and abdomen that allow air to enter the trachea. [More]
- Stigma (plural Stigmata) : prominent cells on the forewings of some moths. Their size, shape and colour can be useful in identifying some species.
