Ceraunus blue butterfly (Hemiargus ceraunus) on candelilla (Euphorbia antisyphilitica). At the Desert Botanical Garden, Phoenix, Arizona.

Ben at benkolstad.net has a wonderful discussion of the etymologies of this critter’s binomial. And I agree, it is the smallest butterfly I’ve seen – about the size of a U.S. dime. 

I see this glyph on every visit to the Desert Botanical Garden in Phoenix, and so far I haven’t been able to find any information about it. It is displayed in the oldest part of the gardens, and could be a Hohokam petroglyph relocated from elsewhere in the valley. The garden was established in 1937 – a time when relics were still collected without restraint or scruple. It could as easily be a modern replica. If anyone has any insight or info, I’ll be grateful if you pass it on.
