Yes, one X marks where I found the specimens for my original colony, and the other marks where I found the ones just last weekend.Does one X mark your recent find and the other your latest?
It's from McAllister's pub, 2013:It does seem likely that they are all A. evides, although you can see on that map that both species were beginning to migrate into each others range... in 2002? Where did you find that distribution map?
McAllister, C. T., H. W. Robinson, M. B. Connior and L. C Thompson. "Millipedes (Arthropoda: Diplopoda) of the Ark-La-Tex. VI. New Geographic Distributional Records from Select Counties of Arkansas." Journ. of the Arkansas Academy of Science, Vol. 67, 2013. 87-93.
Yes, I have one that I didn't post because they weren't quite coupled, and yes, they were mating while still having light colored antennae:Do you have more photos from when they were mating? (I really cannot see their antennae in the one that you uploaded.) I believe that you are correct that increasing the moisture levels stimulated them to mate, but could it be that it did so by first stimulating them to reach a final level of maturity? I find it curious that, as far as I can see, ALL of the photos on BugGuide.net of A. evides have light antennae. To me, this suggests that either they do not live long after reaching this final stage of maturity and reproducing or they are not A. evides after all, but that A. louisianus has migrated further north (and also further assumes that they and not A. evides have dark antennae upon maturity).
Yeah, the short stage of maturity is what concerned me when I first realized this was age coloration. I hope I'm not about to lose my breeders. I have a box full of hatchlings from them, but still, that would eliminate production for a while.
