terrestrial and a large proportion of aquatic insects perform gaseous exchange as previously mentioned under an open system. other smaller numbers of aquatic insects have a closed tracheal system, for example, odonata, trichoptera, ephemeroptera, which have tracheal gills and no functional spiracles. endoparasitic larvae are without spiracles and also operate under a closed system. here the tracheae separate peripherally, covering the general body surface which results in a cutaneous form of gaseous exchange. this peripheral tracheal division may also lie within the tracheal gills where gaseous exchange may also take place.
