I consider Rove beetles to be termite-mimics, which is generally a bad strategy, because everything eats termites. But they do look very much alike, and I have been fooled many times. Termites do have nymph stages, although this is an adult that has flown from its nest to find a mate and start a new colony. This one has already shed its wings. Unless of course this is a species of Rove beetle that is a particularly good termite-mimic!

Are there any other termite species found in Mobile that have reproductives that are this light in color?

I agree that with the light color and the location, this is almost certainly a Formosan termite. There are probably more reliable characters to differentiate the genera on a reproductive caste termite, but I don't know what those characters are other than those found on the wings..

And to think that I identified a newly wingless termite alate just a day or two ago. Shows what happens when one jumps to conclusions, I guess. Many thanks for helping to keep me honest! (And my apologies for the misdirection, Robert.)
