General Information
|
| Term |
non-functional larval spiracle |
ID (Ontology) |
FBbt:00000412 (Fly Anatomy) |
| Definition |
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.[ FlyBase:FBrf0034081 FlyBase:FBrf0064787 ] |
| Comment |
The spiracle of the first tracheal metamere of first instar larvae is non-functional (Manning and Krasnow, 1993). |
