These incredible photos show wasps blowing bubbles or at least that is what it looks like!
The photographer Lim Choo How spotted several of the industrious insects with droplets dangling from their mouths and realised it was time to take some macro photos!
The wasps were flying around a nest, in a factory in Malaysia sucking the water from the surface of their nests and then blowing the water away, to keep their nest dry.
They were actually hoovering up water droplets off their nest and then expelling them as tiny water bubbles so it looked like they were blowing bubbles! Once a wasp expelled a droplet, it flicked the water away with its forelegs.
It is a common behaviour in wasps, particularly among those that live in moist tropical habitats.
