The Aztec Dancer in Arizona had until now not been found later than 26 December (http://azdragonfly.org/news/aztec-dancer-argia-nahuana-pinal-co-arizona-...). While visiting Queen Valley, Pinal Co., on 29 December 2018, Justin Jones and I found 15 individuals of the species (photos below), which extends its known flight season in the state by three days.
