Queen #1
Of the three, she is "shinier". Her gaster was also much more swollen-looking.
Queen #2
Compared to Queen #1, her exoskeleton is dull.
Queen #3
Appearance-wise, she looks like Queen #2 but without wings.
I hope the photos are sufficient enough for an ID. My son believes they are Camponotus but we are unsure of the subspecies. We are also wondering if they are polygynous as we are starting to research formicariums and outworlds to purchase. Because, in all honesty, it would be nice not to have to buy three separate sets. And if they are not polygynous and we decide we can't afford to keep all three (cost-wise and space-wise), what should we do with the other two?
Thank you so much in advance for your advice.
