Fruit fly spiracle, SEM

Fruit fly (Drosophila melanogaster) spiracle. Coloured scanning electron micrograph (SEM) of the spiracle (air pore) of a male fruit fly. Air diffuses into the spiracle and circulates round the flys body in a network of tubes called tracheae. Waste gases then exit through the spiracles. Fruit flies are widely used in genetic experiments, particularly in mutation experiments, because they reproduce rapidly and their genetic systems are well understood.

EDITORS COMMENTS
This print showcases the intricate beauty of a fruit fly spiracle, captured through a colored scanning electron microscope (SEM). The image reveals the air pore of a male fruit fly, known as Drosophila melanogaster, which plays a crucial role in its respiratory system. The spiracle acts as an entry point for air to diffuse into the fly's body and circulate through an elaborate network of tubes called tracheae. These tracheae ensure that oxygen reaches every part of the insect's anatomy while waste gases are efficiently expelled through these same spiracles. Fruit flies have become indispensable creatures in genetic experiments due to their rapid reproduction and well-understood genetic systems. Their use is particularly prevalent in mutation studies where scientists aim to unravel the mysteries behind inherited traits and characteristics. In this mesmerizing photograph, magnified 318 times when printed at 10 centimeters wide, we witness nature's microscopic marvels come alive. The fine hairs surrounding the spiracle add another layer of complexity to this already fascinating subject matter. Through this image from Science Photo Library, we gain insight into the delicate intricacies that make up even the tiniest organisms on our planet. It serves as a reminder that there is so much more beneath our gaze than meets the eye – an entire world waiting to be explored under powerful lenses and scientific curiosity.
