They flies 30km per hour over the surface of the water, and can reach 90km/h on short distances, even as the entomologists claim, 130km per hour. Extremely agile predator, that is why it has exceptionally developed legs. As a larvae live at the bottom of the water and some of them can live up to five years at that stage. They then leave the area and can live for up to 4 months.
Extremely interesting about them is that the scientists claim that one eye is consists of 30000 small eyes so that they have the ability to see on all sides. They ability of flying is so high, that they were seen at 300km from the coast. Like larvae they breathe through the anus. Yes, through anus! They breathe aerated water by means of gills sticking out their anus and spiracles. As adult they breathe through abdomen.
