The other day I photographed this very pretty damselfly in the riparian area over by Sabino Dam.

Afterwards I checked my guides and was unable to identify it.  It just didn’t look exactly like anything in the guides.  So, I contacted Rich Bailowitz, who is an expert on dragonflies and damselflies and asked him if he could help.  He got back to me and advised me that this is a Cerulean Dancer, a species of damselfly that is native to Sonoran Mexico and that was unknown in Arizona before 2012.  It has been found recently as far north as the Gila River, about 75 miles north of Tucson.

I don’t know what accounts for this insect’s recent arrival here.  Of course, it could be related to climate change.  Our relatively warmer and drier weather of late might just appeal to this species.  Or, it could be some other factor.  But, whatever the cause it’s a reminder that nothing in nature is static.  What appears to be permanent actually isn’t and things change, sometimes quite a bit, and sometimes rapidly.  In any event, this damselfly is a little beauty and, as far as I’m concerned, a very welcome arrival on our scene.
