I can pull some old pics at home and do a comparison, but the best way to determine spider is going to be to try to make it wobble. I have plenty of super mojaves, and super mojave spiders but I have never seen a karma spider but it may appear the same as a super mojave under the light. I have a 4 week old non-spider karma I can take a look at under blacklight if you can't tell by wobble. Just flip them upside down.
