There is a video below and some photos of what might be an alate pupae? Its really hard to get crisp quality so sorry.
1. Location doesn't matter, I know the species is Solenopsis, but I'll just add that the colony was keeping their brood extremely close to the surface, I kinda just brushed the test tube along the surface and collected at least 10 larvae/pupae. Air temp was around 25 C / 76 F.
You can see the size compared to adult workers in the video. I observed its body shape to be exactly like that of a queen (large abdomen, thick thorax).
