Callibaetis

This is a female Callibaetis imago. The species is probably C. ferrugineus. (There are two subspecies, C. ferrugineus ferrugineus and C. ferrugineus hageni.) The subimagoes that you describe are probably the same species; they have darkish wings with white veins that form a network of thin white streaks.

female?

How can you tell its female?

… Borealfalcon, 26 August, 2008 - 9:52pm

Gender

The male Callibaetis imagoes have large distinctive eyes (the eyes are turbinate and are also obvious in the subimagoes), long forelegs (for grasping the females during aerial mating), and the male terminalia (especially the forceps or "claspers") will be visible at the tip of the abdomen.

You mean..

Now I did a bit of research..the subimagos have smoky wings with wings veins?? I always thought those were different species. Since I have seen trace of subimagos in both patterns.

Subimagoes

Using your other photos as examples, here is a female subimago, and here is a male subimago. I believe these are also C. ferrugineus.

C. ferrugineus

At the beginning of this thread you commented that this was probably C. ferrugineus. Have you done enough additional research since then to say that this IS C. ferrugineus? Also, if you believe that the male/female images are C. ferrugineus, then would you mind making that ID on those images - I would be glad to move all of these images to their proper species page.

… Ted Kropiewnicki, 13 September, 2008 - 7:18pm

Done

Identification to the subspecific level would be based mostly on distribution, and I was unable to locate verifiable records at that level.

… Lloyd Gonzales, 14 September, 2008 - 12:47pm

No I don't mind, but if it get a species page Id rather have the main pic with it. If no-one can I.D. I will probably find somewhere where I can get the specimen I took dissected.

… Borealfalcon, 25 August, 2008 - 8:12pm

Not an ID but...

I cropped your picture. Hope you don't mind but it makes it much easier to see the insect when it fills the frame. I will replace it if you would like.
