[Note Guidelines] Photographer's Note
Maine Snaketail, Ophiogomphe du Maine
(Ophiogomphus mainensis)

Adult size: 42-46 mm

Habitat: This species is mainly associated with clear, rocky woodland streams and smaller rivers, frequently where they drain marshes or lakes.

Flight period: In New Brunswick, emerges in late May and flies to mid-August(dates May 10th- August 10th)

ID hints: The only snaketail in our region normally lacking dorsal markings on S8 and S9. Indeed, segments S1 to S7 have the narrowest pale yellow dorsal streaks in the Snaketails here, which occasionally also occur on S8 and most rarely on S9. Riffle (O. Carolus) and Brook Snaketails (O. aspersus) have wider dorsal stripes than this species. Boreal Snaketails (O.colubrinus) have a cross-line on the face which is absent from this species, as well as both the Riffle and Brook Snaketails and a few more.

General Nature Notes: Common to abundant along a number of the cleaner, swifter-flowing watercourses in New Brunswick, this is the second most easily spotted of the seven species of Snaketails in our region. Like the Riffle Snaketail, this species perches on stones or boulders, but it prefers these features near more gentle rapids. It is also decidedly more wary than the Riffle Snaketail. Away from water, this species tends to feed in fields. In flight, it is often seen flying low above riffles and rapids. During the day, like other members of the genus, it will perch (frequently) in the crown of trees, making it very difficult to locate and belying its actual abundance. Early in the evening, this species becomes less wary and more active in shaded areas, often perching on rocks and overhanging leaves.

Hello Denis, You nailed it this time!!!
Focus is tac sharp, colors are true and natural and the DOF is great. I'm not sure what the BG actually is, but I love the color scheme. I'm guessing it is a brackish colored pool of water. Very informative notes. Outstanding Image!!
