![Gold Star Critiquer/Gold Star Workshop Editor/Gold Note Writer [C: 663 W: 98 N: 1260]](http://i1.treknature.com/misc/g-g-g.gif) (4181) | Last week I went back to the large pond where I have seen so many dragonflies lately. I walked slowly around the edge and suddenly I spotted a large dragonfly species that I had never seen before. She was in her egg depositing behavior, hovering about a foot above the water for a few seconds and then dropping down, dipping here abdomen tip to the surface, and then rising to hover again.
I believe this is the first Jade Clubtail to be posted to TrekNature.

Identification:
The Jade Clubtail is a distinctive grayish jade green with abdominal segments 7 to 9 rust-colored. Segment 10 and the claspers are pale yellow. It lacks an abdominal club. The thorax has a brown shoulder stripe and the abdomen is marked with green. It has green eyes and pale legs. The female is similar to the male. The bridge (occiput) between its eyes is straight-edged or slightly notched in the middle. It tends to perch on logs and branches protruding from water near the edges of lakes.
Size:
Total length: 51-55 mm; abdomen: 37-41 mm; hindwing: 34-36 mm.
Similar Species:
Stillwater Clubtail (A. lentulus ) has well-developed dark humeral stripes and abdominal segment 8 is generally darker than 7 or 9. The male cerci are shorter and more compact than in Stillwater Clubtail. Bayou Clubtail (A. maxwelli ) is smaller and generally darker (brown not reddish ) with more well-defined thoracic stripes.
Habitat:
Semi-permanent and artificial ponds, lakes and slow-areas of streams with muddy bottoms.
