May 11, 2016
Location: Oak Flat Mine Pond

In the US, the Claw-tipped Bluet is largely confined to Arizona and within the state, is found mostly at locations in the southermost counties (Bailowitz et al., 2015). On 7 May 2016 one male was found by Justin Jones at Kelvin Bridge and this observation represented the northernmost state record for this species. Further extending the northern range limit of the bluet, three males were found on 11 May 2016 at Oak Flat Mine Pond (1216 m.a.s.l.), which is situated 22.5 km north of Kelvin Bridge. This is the northernmost location where the species has been found to date in Arizona.
