Images I took using Scanning Electron Microscopy (SEM), showing a bug with silvery looking hair which amazingly the colour is structural and not pigment as your eyes could suggest and the focused image showing many lenses in the eye of the bug. one eye could contain hundreds of the small 25 micron wide hexagonal shaped lenses, that serve both for sight and camouflage as the facets have anti-reflection properties. so next time before you swat a fly think how complex it is and what we could benefit from understanding their structures.
