Over the past few weeks, I've been checking suspected locations for Smoky Rubyspot (H. titia) along the Rouge River in Wayne County, Michigan. Today, under cloudy skies and a temperature of 60F, I finally succeeded at Levan Knoll!
The west end of this area has a one-lane bridge and is just downstream of a high quality water area identified by Friends of the Rouge. Upon arrival at the riverbank, three American Rubyspots (H. americana) flew up. Here is one of the males:

On the opposite bank, a downed tree and gravel bank provided good perching opportunities for more rubyspots. Then I saw saw the true habitat requirement for H. titia... a half-submerged barrel:

This species has now been confirmed on three rivers in Wayne County, Michigan (Detroit River, Huron River, Rouge River).
