Spiracle Collection

Eye and spiracle detail of a Bluespotted / Ribbontail Stingray (Taeniura lymma) Sipadan Island, Sabah, Borneo, Malaysia. May

Mustelus canis, Smooth Dogfish, side view

Fruit fly spiracle, SEM
Fruit fly (Drosophila melanogaster) spiracle. Coloured scanning electron micrograph (SEM) of the spiracle (air pore) of a male fruit fly

Ant spiracle, SEM C018 / 0551
Ant spiracle, coloured scanning electron micrograph (SEM). Spiracles are openings in an insects exoskeleton that connect to the tracheal tubes which deliver oxygen directly to tissues within

Anopheles stephensi mosquito larva. The head is at left, the tail at right. The adult Anopheles stephensi female is a known vector for the tropical disease malaria

Culex mosquito larva C017 / 8352
Culex mosquito larva, with a breathing tube, on the waters surface. Mosquito larvae have a well-developed head (upper right) with mouth brushes used for feeding and propulsion

Large white butterfly larval spiracle SEM
Large white butterfly (Peiris brassicae) larval spiracle, coloured scanning electron micrograph, (SEM). Air diffuses into the spiracle

Silk moth caterpillar breathing pore
Silk moth caterpillar air pore. Polarised light micrograph of a spiracle (air pore, upper centre) and its attached tracheae (air passages) from a silk moth caterpillar (Bombyx mori)

Warehouse moth larva, SEM
Warehouse moth larva. Coloured scanning electron micrograph (SEM) of part of the body of a warehouse moth (Ephestia elutella) larva or caterpillar. There is a spiracle (brown) in each body segment

Breathing tube on a fruit flys pupa, SEM
Breathing tube on a fruit flys pupa, coloured scanning electron micrograph (SEM). This structure is called a spiracle. This fruit fly is Drosophila melanogaster (wild type Oregon R)

Adult fruit fly hatching, SEM
Fruit fly hatching. Coloured scanning electron micrograph (SEM) of an imago (adult) of the fruit fly Drosophila melanogaster (wild type, Oregon R), at eclosion (hatching)

Insect anatomy, artwork
Insect anatomy. Computer artwork of a cross-section through the body of a typical Insect showing the main structures and organs. For the labelled diagram see image: C008/8724

Fruit fly pupa case, SEM
Fruit fly pupa case. Coloured scanning electron micrograph (SEM) of the inner surface of a pupal case, or puparium, of a fruit fly (Drosophila melanogaster wild type Oregon R)

Caterpillar spiracles, light micrograph
Caterpillar spiracles. Light micrograph of part of the skin of a caterpillar showing part of the tracheal system for bringing oxygen to the body tissues

Mosquito larva, light micrograph
Mosquito larva. Polarised light micrograph of the body of a larva of an Anopheles sp. mosquito. The larva lies parallel to the waters surface

Caterpillar skin, light micrograph. This section of part of the skin shows two half segments. The skin is covered in small hairs or setae (black), and brown structures called tubercles and verrucae

Caterpillar spiracle, light micrograph
Caterpillar spiracle. Polarised light micrograph of part of the skin of a caterpillar, showing an air hole (spiracle, dark oval, lower right) leading to a breathing tube (trachea)
