Change of morphometric and allometric patterns on wings of banded demoiselle (Calopteryx splendens) males in case of ecologically different watercourse types

In the nature, larvae living in watercourses are exposed to a complex system of environmental influences. It is known that different watercourse types (creeks, brooks, streams, little rivers and medial rivers) provide conditions for larval development (water depth, flow rate, temperature, oxygen content, substrate type, nutrient supply, etc.). These can vary significantly between types, but be very similar within types. this work, we examined body sizes wing morphometric characteristics males Calopteryx splendens reared from (brook, stream, creek, river, river). Although there were no significant differences size among found features. We most individuals streams creeks stream river. Our results show clearly separated on two wings. The also suggest number pattern allometric features wings
