Orange Barred Sulphur, Large Orange Sulphur Or Cloudless Sulphur Butterfly?



UPDATE:  Nancy Greig, Ph.D., Curator of Entomology at the Cockrell Butterfly Center confirmed that the Butterfly is indeed an Orange Barred Sulphur!

Let me start this post by saying I can’t figure out what type of Sulphur Butterfly this is.  I’ve sent out some emails for clarification, but if anyone can help me I would appreciate it.

I was watering the lawn today and noticed this very large, yellowish-orange thing fall (at least it appeared to be falling) into the grass.  As I got a closer look, I noticed it was a Butterfly and it was drinking water from the grass.  If you look closely at the picture, you can see the protruding proboscis.

After drinking a bit of water, it flew up to the Bamboo where it rested for a good 5-10 minutes.

Here’s my problem with this Butterfly.  It looks awful orange to be a Cloudless Sulphur.  It also has that dark rim around the edge of the wings that I don’t believe Cloudless Sulphur Butterflies have.  When I looked in my Butterfly books, there is mention of an Orange Barred Sulphur, but that is supposed to be a rare visitor to the Houston area.

When I did a search on the Internet, I found this page (Butterflies Of The Carolinas and Virginias) and looking at the second photo, it looks quite similar to the Butterfly above.

Can anyone help me positively identify this Butterfly?  Again, I’m located in Houston, Texas, in the Northeast section if that helps.
