Butterfly wings work like LEDs

[n2doc]

When scientists developed an efficient device for emitting light, they hadn't realised butterflies have been using the same method for 30 million years.
Fluorescent patches on the wings of African swallowtail butterflies work in a very similar way to high emission light emitting diodes (LEDs).

These high emission LEDs are an efficient variation on the diodes used in electronic equipment and displays.

The University of Exeter, UK, research appears in the journal Science.
