This is a teneral Blue Corporal dragonfly. Young males and females are brown rather than blue.

Blue Corporal dragonflies are classified as endangered in Ohio. However, this status will probably be reassessed soon. Blue Corporals are rapidly expanding their presence in southwestern Ohio, and they are now quite common. The individual at left was found at Oakes Quarry in Fairborn. 

This is another teneral Blue Corporal, hanging out at Cox Arboretum. In addition to Cox and Oakes Quarry, I have also found Blue Corporals at Germantown MetroPark, Twin Creek MetroPark, Caesar Creek, Grant Park in Centerville, and Spring Lakes Park in Bellbrook. 

This male Blue Corporal is younger than the individual above. He is in the process of turning blue, but he has not yet developed his full color. The pale, thin stripes on the front of the thorax are more apparent in younger individuals. 

A more mature female, resting on a leaf at Twin Creek MetroPark. This species has been spreading rapidly in the few short years that I have been watching dragonflies, although it seems that their expansion has been hindered somewhat by cold spring weather in 2020 and 2021. 

Blue Corporals are one of our earliest dragonflies to emerge locally in the spring. They fly in April and May, with occasional stragglers into early June. My personal early sighting is April 14th, and my late date is June 9th. (Blue Corporals are scarce after the end of May.)
