The photos in sequence after the first (which was selected out of sequence to show full image). Single ant struggles with what looks like the head of a dead flower with an imbedded seed. Pushing the larger than ant object, she veers near and then far from the opening to the nest. At another pass toward the hole, a second ant joins it and they manage to get it closer to the hole. At which point a third, and possibly 4th ant joins them and they successfully get it down the hole.
