International consortium guided by P. Vršanský contributed to knowledge on evolutionary dynamics of aquatic insects. Comparative material was calibrated at 300, 270, 220, 151, 127, 115 and 98 Ma. For study of living equivalents, two expedition to primeval rainforests were conducted (UNESCO BR SUMACO, Equador). Discovery resulted in global analysis of all aquatic animals. 6 000 records of evolution of aquatic insects from the Mississippian to the present reveal that insect are incapable of returning to land once adapted to aquatic lifestyle. Originally, the partition of aquatic groups was small, and this ratio stabilized during the Triassic and is for nearly 250 million years constant. Majority aquatic lineages still survive, which is contrary to terrestrial lineages. In insect history 236 invasions to water occurred, but reversal is absent at all (0). This contrast with vertebrates, which frequently return to land. Thus it is doubtful that the first insect was aquatic. Living aquatic cockroaches in Ecuador swim extremely rapidly (1 ms-1) and though they are without a single macroscopic adaptation, adaptations are disclosed in nanosurfaces. They belong to the most progressive lineages.
