non-functional larval spiracle [FBbt_00000412]

Spiracle that only opens during moulting, allowing ejection of the chitinous lining of or the trachea of the previous instar. The rest of the time, these are only identifiable as a thickening of the cuticle. During larval stages, the spiracles of tracheal metameres 2-9 are all of this type. The spiracle of the first tracheal metamere of first instar larvae is non-functional (Manning and Krasnow, 1993).
