Sweetflag Spreadwing (Lestes forcipatus)

Identification: Challenging! Male in comparison to disjunctus can be puzzling with a number of features such as basal and distal cerci teeth, paraprocts, S2/S3 length comparison, S10 posterior shape, pruinosity, thorax spot, etc. taken together to get a true ID.
