We have been finding lots of mosquitoes, mostly larvae as well as pupae (see picture above) and adults. The pupae live in water for up to 4 days and do not eat during this stage. They are found floating at the surface taking in oxygen through two respiratory trumpets on the top of the cephalothorax (the head and thorax are fused). The abdomen is made up of moveable segments with two paddles at the end. The pupae are referred to as ‘tumblers’ as when they are disturbed they dive in a tumbling motion and then float back to the surface. The adult mosquito emerges from the pupal case straight to the surface.
