Summary[edit]
| Description |
Français : Animation montrant trois osmies bicornis fécondées au travail. En bas, on observe une osmie obturant par une cloison maçonnée le bambou qu'elle a entièrement rempli de ses larves (celles-ci sont séparées, dans le bambou, par des cloisons maçonnées). Au milieu on observe un autre osmie qui se pose et entre dans son bambou (pour y pondre ou y maçonner une cloison). En haut on observe une osmie qui effectue un retournement : elle a dû finir de maçonner avec sa tête et se prépare, en rentrant abdomen en premier, à pondre une nouvelle larve. Par raison d'économie (de poids du fichier .gif), la boucle de cette animation ne montre pas certaines actions nécessaires des osmies (comme, par ex., redécoller ou se poser pour l'osmie du haut). Le faible poids de cette animation a été obtenu par l'usage intensif de l'écran vert dans le logiciel libre GifCam ; Ce logiciel a ici divisé le poids de l'animation par 15.
English: Animation showing three fertilized osmia bicornis at work. Below, we observe an osmia masoning the bamboo which it has entirely filled with its larvae (these are separated, in the bamboo, by masonry partitions). In the middle we observe another osmia which lands and enters its bamboo (to lay eggs or build a partition). At the top we observe an osmia which is reversing itself: it must have finished masonry with its head and is preparing, by returning abdomen first, to lay a new larva. For reasons of economy (the weight of the .gif file), the loop of this animation does not show certain necessary actions of the osmia (such as, for example, taking off again or landing for the top osmia). The light weight of this animation was obtained by the intensive use of the green screen in the free software GifCam; This software has here divided the weight of the animation by 15. |
