November 6, 2016
Location: Dudleyville ponds

The Three-striped Dasher is a tropical species that in the US, had until now been found only in Texas and South Florida. It is also found in Mexico, where known populations in Sonora occur approximately 300 miles south of the US border (Bailowitz et al., 2015). On 6 November 2016 a male, shown below, was discovered at the Nature Conservancy Preserve ponds in Dudleyville, Pinal Co. This site is located approximately 420 miles north of the closest known locations where the dasher is found in Sonora, Mexico. This observation provides a first state record of the species and also the northernmost location where it has ever been found.
