Butterfly wings are really fascinating when they come ... Erase all the small circles and the body line from the first step.

Another theory is that the butterfly looks like a gecko on tree trunks, which real geckos (a major predator of this species) would avoid. David says, 'Wings sometimes bear patterns that conjure up ...

Here, we reconstruct the body and wing kinematics of a forwards-flying butterfly based on high-speed images. Using an in-house computational fluid dynamics solver, we simulate the unsteady flow field ...

A vapour sensor based on an exact replica of the butterfly-scale design will most probably be unable to selectively quantify more than ten individual vapours from their mixture. A man-made ...

McCloskey advances on the butterfly, its body immobilised on the table with a loop of wire. One of its wings is stretched out - black inky veins running through a delicate orange membrane.

Disease name: Epidermolysis bullosa (EB), or "butterfly disease" Affected populations: Butterfly disease is estimated to affect around 1 in 50,000 children, if you count all subtypes of the ...
