Hi... I know this is an old thread, but I thought I'd give it a try. We've been purchasing both Calciworms and Reptiworms for you our A. Maculatum. They prefer the Calciworms for whatever reason, even though they smell like vinegar and are $3.99 for roughly 7 larvae (we're feeding 6, obviously that makes no sense and I don't know why Petco sells such small amounts). The Reptiworms are healthier looking and much more cost effective. We've been getting them online.
The reason some are black and some are cream colored is due to molting; they get nearly black before they molt, moving onto another "size".
