Late Spring Azure? - Celastrina - female

Late Spring Azure? - Celastrina - Female
Norris City, White County, Illinois, USA
May 7, 2007
This butterfly resembled an Eastern Tailed Blue, only it was half again as big as a normal Eastern. Plus, the markings on the wings were almost non-existent. An Eastern Tailed Blue normally has two bright patches along the lower back wing and a pronounced tail - those weren't there. Could this be another species or just an aberrant Eastern? I'm pretty certain it was a female, too, for it seemed to be laying eggs on this stand of clover.

Moved
Moved from Frass.

Frassed
Moved from Echo Blue.

 
It does seem to be laying eggs
on what we guess is the flower head of clover. We would be tempted to keep it in the guide because we don't have many images of oviposition. What do you think? Can we move it back? We just got back to find all these frassed images and don't want to interfer with whatever is happening, but think we should reconsider this one.

 
Advice
Well, the reason this image is here is because somebody told me that the Echo Blue Azure is strictly a West Coast species. This is probably just a Spring Azure and should be renamed. If that's the case, by all means, it should be in the Guide. I just don't want it in the wrong area. What's your advice? Rename it, correctly, and move it there?

 
We will move it to the genus page
Celastrina, where Dr David Wright will probably look at it later in the year and clarify which of the eastern blues it is.

 
Thank You
Thank you for doing that!

What do you think
of an Azure, say, maybe an Echo Blue (Celastrina echo)?

 
Former Name
Did this species used to be called a Spring Azure? If so, I found some pictures online and they looked exactly like this butterfly. One website called it an Echo Blue Azure, formerly Spring Azure. According to Butterflies and Moths of North America, they are found around my area, so I think you've hit it right. Thanks for the help in identifying this one. Now I can add another species to my records for White County, Illinois.

 
At one point, almost all Spring Azure-like
butterflies were part of one big Spring Azure complex. It wasn't until recently that certain "races" were raised to species status. For example, last week I sighted several Late Spring Azures (Celastrina ser*otina), which are a considerably "new" species which had received species status in 2005 (thus many websites and literature sources have become outdated). It formerly went by the same common name, but was considered to be part of the Spring Azure species. Other Azures such as the Echo Blue have had similar revisions. Hope that answers your question.

 
Thanks!
Thanks for the info!
