Dynamics of seasonal activity of imago of Geometrid moths (Lepidoptera: Geometridae) in the south of the Amur Region
Dynamics of the occurrence of imago of Geometrid moths was studied based on the observations in the southern part of Amur Region in 1997-2015. In total, 2696 specimens belonging to 284 species of Geometridae were taken into account. The flight dynamics of individual subfamilies with a preliminary assessment of their similarity are considered. Seven phenological groups were distinguished: early spring, spring, early summer, mid summer, late summer - early autumn, late autumn, as well as a group with two generations, which is divided into early summer - late summer and mid summer - early autumn subgroups. The dynamics of the activity peaks of Geometrid moths in the south of the Amur Region is similar to that in the Zeysky and Bolshekhekhtsirsky reserves, has differences from the territory of the Lower Amur Region and correlates with weather and climate factors.
