Baja Bluet, Enallagma eiseni, in Pinal Co., AZ: northernmost record to date.

November 10, 2018
Species: Baja Bluet
Location: Kelvin Bridge

After a hiatus of approximately 10 years without any recording in Arizona or elsewhere in the US, in October 2018 multiple Baja Bluets, Enallagma eiseni, were again found at the Quitobaquito pond in Pima Co., the only Arizona location where they were known to occur for several years.

 

Most unexpectedly, on 10 November 2018 a single male of the species (photos below) was discovered along Mineral Creek at Kelvin Bridge, Pinal Co. This observation provides the northernmost record anywhere of this typically Baja California (Mexico) endemic.
