If you look at their wings, you can see they are very large and broad compared to the size of their body and aren't considered to be very aerodynamic. but this to make of clapping and cupping now appears to have given them an evolutionary advantage. thinking is this technique developed by the humble butterfly could be applied to modern tech allergy to make drones and underwater vehicles faster, travel further and last for longer. laura foster, bbc news. just a reminder that later today in washington, it will be the inauguration, handover of powerfrom president biden. the time now in washington...
