Alright I just got a chance to get some belly shots, I'd really like to learn what I'm looking for so I have more pics of the bumble bee in question and then a couple pics of 2 other combos I have that were sold with yellow belly as one of the morphs. Looking at them I have no idea what I'm even looking for so hopefully someone can see it and explain.

Here are two that are supposed to carry yellow belly
