additional two photos attempt to show the appendages, with my limited camera, of a pair that curved in and then out at the tip
This photo of a tandem pair extend the known dates in Monterey County from 22-29 Oct 2006. Details about this first population in the county are at https://www.inaturalist.org/observations/239705547
I found a male, a female, and this tandem at the dry pond mentioned in the prior observation.
