Eight-spotted Skimmer

Description:

It has two black spots on each wing for a total of eight, and can be distinguished from the similar Twelve-spotted Skimmer by counting the spots. Adult males are additionally adorned with opaque white spots between the black ones. It can be found west of the Rocky Mountains near muddy bottomed ponds and lakes.[3] East of the Sierra Nevada Mountains, some females may also have white spots, making them the only female dragonflies in North American white spots on the wings.[4] The total length is 44 to 50mm. Flight season is April through October
