These Florida harvester ant minor workers have found a tasty and nutritious seed to add to their granary and are working together to trim the pappus bristles off for better transport & storage. I once saw them try to take a large sandspur (Cenchrus incertus) seed into the opening of their colony, even though it was too tough to trim and would not fit. After many tries they discarded it. The seed in this photo will fit nicely. If you visit these fascinating creatures, know that they are not aggressive and usually quite amiable but they do have an extremely potent & long lasting sting...so stay on their good side!
