Actually, most species in the US are a Antaresia maculosa x Antaresia childreni anyway. They were crossed when they first started being imported (before the species were properly identified). Given the lines are quite a bit cleaner now, but that doesn't fix the damage already done. There are also pure lines, but most are a distant cross.

If I remember correctly, Spotteds have a more irregular pattern (spot) and they tend to be much darker as adults. Children's are much lighter adults, with more of a round pattern (spot).

Of course every species does have an exception, and I'm just stating general appearance. I concur though. Judging by appearance, I'd say that animal leans heavily towards being a Spotted.
