Abstract: It is believed that Lepidoptera are among the organisms most affected by global warming, which significantly influences their development cycle, reproduction and even survival. Moreover, generations of Lepidoptera are short and reproductive rates are high, so they are likely to respond more quickly to climate change, compared with bodies which have a long cycle life such as plants and vertebrates. Lepidoptera response to climate change: Lepidoptera climate change can manifest itself in changes of distribution (area expansion or reduction of propagation), phenological changes, changes the nature of evolutionary changes in interrelations with other types of organisms Lepidoptera. If Lepidoptera under the influence of temperature increase, reduce development time and adult emergence occurs earlier. Thus, increases during the flight. Research conducted in Romania, in Dumbrava Sibiului Forest showed that an increase in average temperature increase of only resulted 1oC flight period of two to 10 days, especially multivoltine species.
