I was very lucky in being able to get a good photo of the female too, especially with this being a new species for me. The females were more shy, I didn't get as many shots of them. One finally swam into the sunlight. The female does not have the white stripe on top of the head or the green on the head. Her under the tail area is speckled, not black like the male. Click on the right arrow to see the male for comparison.
