Structural colour

Here is a video I made to demonstrate structural colour. The blue colour on these butterflies’ wings is produced when light passes through nano-metre scale structures and the interfaces between these and the surrounding air. When ethanol is dropped onto the wings these air spaces are filled in and so the colour changes. The video is at 2x actual speed, so you can see that the colour comes back when the ethanol evaporates.

Butterflies in the Winter Gardens!

On the 25th and 26th of March we are going to be displaying some of our work and our live butterflies in the Sheffield Winter Garden. Come along to escape the wintery weather and find out about tropical butterflies and their colours! We will be on-hand to explain what we do and why we think butterflies and their colours are interesting.
