The First ant walks into frame and senses the nyjer seed using the antennae and forelegs and attempts to grasp the object. The ant searches repetitively along the length of the seed. Another ant walks in and senses and manipulates a dandelion seed that is out of focus. The ant sensing the nyjer seed walks away and another ant quickly senses the seed with its antennae the walks away. Other ants walk over the nyjer seed without attempting to manipulate it while the dandelion seed is manipulated in the background. |

☑️ - Manipulated or Pinched - No Grasp |
The ant interacting with the nyjer seed senses using its antennae and manipulates the seed using its fore, and mid legs. Other ants walk through and interact with the seed by sensing it using antennae then walking away. The ant makes multiple pinches on the nyjer seed with the mandibles, and in the background, a dandelion seed is manipulated and removed however this interaction is not in focus of the cameras. There are multiple ants sensing and manipulating the nyjer seed simultaneously. An ant walks through the scene carrying another seed, interacts with the ant sensing the nyjer seed then leaves, then returns a number of seconds later and re-grasps this other seed in the centre of the field of focus of this video. The nyjer seed is not taken away, but is sensed and manipulated once more at 2:46. |

☑️ - Manipulated or Pinched - No Grasp |
Researcher moves seed to the centre frame. At 0:30, ant approaches the seed and senses it using the antennae and forelegs. The ant scans along the seed and senses using its mandibles, the ant also manipulates the seed using its forelegs. Another ant approaches the seed and senses it at the same time but moves away and senses another seed in the scene instead. The ant initially sensing the seed moves to eat a substance on the ground of the arena. Another ant approaches and the two ants touch antennae, and the first ant then exhibits cleaning behaviours, moving the forelegs along the antennae. This ant then returns to sense the nyjer seed and make some grasp attempts while lifting the seed using its forelegs. Another ant joins to sense and manipulate the seed but walks away without grasping. The ant remaining on the seed makes several grasp attempts, moving away at approximately 2:00. The full video contains multiple ants sensing and attempting to grasp two different seeds in the camera views, but no ants successfully grasp or lift either seed. 2:44 to 3:02, and 3:27 to 3:44 show good examples of the scanning behaviour that occurs when an ant is searching for a grasp. |

First ant moves into the scene and senses the object, also manipulating it with the forelimbs. Another ant arrives shortly after to sense the object simultaneously but does not manipulate it. A third ant senses the object and leaves without manipulating it. A fourth ant arrives and senses the object, and manipulates it using forelegs before it grasps using the mandibles and carries the seed away. |

✅✅ - Grasped and Carried Away |
First ant senses the object using its antennae then walks over the seed as it leaves. The second ant senses the object with the mandibles as well as antennae and forelimbs and makes some grasp attempts, lifting the seed off the ground then lowering the seed again without walking. At 0:33 a larger ant begins interacting with the seed and attempts to grasp it at the same time as the second ant. The larger ant manipulates the seed using its forelegs and grasps the object using the mandibles and lifts the seed off the ground. This larger ant spends a few frames cleaning itself before carrying the seed away. |

☑️ - Manipulated or Pinched - No Grasp |
First ant approaches the seed with mandibles wide open then relaxes as it gets nearer to the seed. This ant uses its forelegs to pull the seed towards the body as the mandibles pinch along the edge of the seed, while the antennae also tap and drag along the seed. The ant also uses its mid-legs to hold or manipulate the seed. It cleans its antennae while standing over the seed then walks away. Multiple other ants enter the frame during the video but no others interact with the seed. |

Long Video. Multiple ants approach, crawl over and sense the object. Many using the mouthparts under the mandibles, perhaps drinking any liquid possible from the object. One of the ants attempts to pinch the ring but it did not successfully grasp the object. Another ant makes sequential attempts to pinch the object around the ring’s circumference. One ant pinches and grasps the ring but does not manage to move the object, it then continues to move around the ring perimeter continuing to make pinching motions around the objects edge then walking away when it encounters another ant. Two more ants making pinching action around the circumference of the shape, following its edge. Eventually one of the ants successfully initiates movement of the object while two other ants are crawling over the object. The ants continue to manipulate the object, but not in the view of all cameras. |
