Pulvilli on a flys foot, SEM

Flys foot. Coloured scanning electron micrograph (SEM) of pulvilli (tubular hairs) on the base of the foot of a fly (order Diptera). Each pulvillus secretes a solution that forms a bond with the surface on which the fly is standing. This allows the fly to walk on vertical surfaces, or even upside down

EDITORS COMMENTS
This print from Science Photo Library showcases the intricate pulvilli on a fly's foot, revealing the remarkable world of insect anatomy. In this colored scanning electron micrograph (SEM), we are granted a close-up view of the tubular hairs that make up these pulvilli. These tiny structures play a crucial role in enabling flies to navigate vertical surfaces and even walk upside down. The pulvillus secretes a specialized solution that forms an adhesive bond with any surface upon which the fly lands. This extraordinary adaptation allows these agile creatures to effortlessly explore their surroundings, defying gravity with ease. The false-colored image highlights the complexity and beauty hidden within nature's smallest creations. Through this lens into entomology, we gain insight into how insects have evolved to thrive in diverse environments. The magnified image reveals every minute detail of these hair-like tubes, emphasizing their importance for adhesion and stickiness during locomotion. This photograph not only captures the wonders of zoological exploration but also serves as a testament to scientific progress enabled by cutting-edge technology like scanning electron microscopes. It reminds us that there is still much left to discover about our natural world, particularly when it comes to its smallest inhabitants – insects like this fly whose feet hold secrets essential for survival in their miniature universe.
