Davis, Yolo County, California, USA
May 15, 2007
At first, I thought this was a blue dasher because I had seen so many others that same day, but now I can see that the wings are lacking the amber color near the base. I can't really make out much datail in the face so I have to go off the wings. None of the other similar species in CA (bleached skimmer, comanche skimmer) are supposed to have clear wings except for the western pondhawk so I'm going with that. I would appreciate any comments in case I'm missing something though.

@Rod and Timothy:
While I am very impressed that the system at bugguide works as good as it does, there does seem to be something amiss here. If you look at the bleached skimmer page you see this photo, however, when you click on it you end up viewing it at its intended location, the Blue Dasher - Pachydiplax longipennis section in the guide. I'm not quite sure how that can happen, but this is a pretty complex data base.

The reason for my repeating Rod's comment is that, going by the indentation, Rod actually responded to my comment, not to Timothy's and it may be possible that only I received notification, and I have no way of correcting the situation since it is not my page and I am not an editor, so I am just (possibly) passing it along.

Moved from Western Pondhawk.

Blue Dasher Pic in with Bleached Skimmer
In reviewing pictures of the Bleached Skimmer I found a picture of a Blue Dasher you had intended to relocate from Western Pondhawk. I am not too well versed in making these moves or would have handled this myself. Please go to the Bleached Skimmer photos and you will see what I mean.

Western Pondhawk is Erythemis collocata

There is a name mismatch in the title of this post!
Some editing needs to be done here!

I think it is in the right location now (Blue Dasher) mainly because the eyes seem greenish.

Right the first time?
That's my take - Blue Dasher. I'm basing that on the light color of the eyes, as opposed to the deep blue of the Western Pondhawk. Check some other images and see what you think.

for your input, Ron. I agree that the eye color is much closer to that of other blue dashers. And after taking a very close look at the original photo again, I see that there is just the slightest hint of amber coloration at the base of the hind wings (see new image). I think that's enough to move it back with the blue dashers (although a clear shot of a white face would have been nice for added assurance). Thanks again...and I'll try to not be so quick with my IDs in the future. =)

As per our recent discussion on the Western Pondhawk
As per our recent discussion on the Western Pondhawk, Ron, am I correct in guessing that you are in agreement that this is a Western Pondhawk (Male). BTW, the females are a shocking colorful green!

I'd say Blue Dasher
because of the eye color.

Yes, we are in agreement here!
Also as you know, the Blue Dasher has a somewhat large patch of amber on the proximal end of the second pair of wings...

Moved from Blue Dasher.
