Black-shouldered Spinyleg

Just about a year ago, and, while I don't have great records, probably at about this time in 2012 and before, I spotted 2013's debut Black-shouldered Spinyleg dragonfly. Dromogomphus spinosus is quite common around here, but you have to know where to look for it. For who knows what reason, this striking odonate, a member of the Clubtail group, makes its debut on a millpond boulder I frequent as a viewing post, and today I found it sunning itself on that very spot. This was one of the first Clubtail dragonflies I learned to identify, and it's pretty distinctive, with the bold yellowish markings on the thorax and abdomen, those bright, completely separated green eyes, and, of course, the very long hind legs with their signature spines. According to the field guides, this species should have been out and about since late June, but I've never seen them until the last week of July. That date has arrived and with it, D. spinosus posing on my observation rock. Can the Dog Days be far behind?
