This blood-feeding fly sacrifices its sight after finding a host
Researchers have discovered that deer keds, a type of blood-feeding fly, undergo a biological transformation that reduces their visual sensitivity after they settle on a host. This shift allows the insects to redirect energy from vision to their new life as permanent parasites.
Why it matters
This study provides insights into evolutionary biology and how sensory systems adapt to extreme changes in an organism's lifestyle and environment.
