This week, we completed our group Creature Study Presentation. Our topic was Insects & Bugs: Arthropod Locomotion in Animation. We mainly studied how different insects and arthropods move, and divided our research into three types: flying, such as bees and butterflies; walking, such as ants; and crawling or wriggling, such as centipedes and caterpillars.
There were three people in our group, and each of us focused on a different type of movement. I was responsible for flying insects, especially bees and butterflies. Through the research, I found that bees and butterflies create very different feelings in motion, even though they both fly with wings. Bees have compact bodies and small wings compared with their body size, so they need very fast and high-frequency wing beats to stay in the air. Their flight is usually direct, stable, and purposeful. They can move quickly between flowers and also hover before landing. In contrast, butterflies have light, slim bodies and large, flexible wings. Their flight is slower, softer, and more floating. Their wing movement has a larger amplitude, and their body often moves up and down along a wavy path.
Another group member researched ant walking movement. Ants have six legs, strong jointed limbs, and clear body segmentation. Their main gait is the tripod gait, which means three legs support the body while the other three legs move forward. This alternating rhythm helps the ant stay balanced while walking. The leg motion can be divided into four stages: lift, swing forward, touch down, and push back. During walking, the ant’s body also has a slight sway and small adjustments when changing direction.
The third group member focused on centipedes and caterpillars. Centipedes have many repeated body segments, with each segment connected to a pair of legs. Their movement uses a metachronal wave gait, where the legs move one after another and create a wave-like rhythm. The front part of the body moves more to control direction, while the back follows with a delay. Caterpillars move in a different way. Their motion mainly comes from the body rather than the legs. The soft body compresses and stretches, creating a wave that travels from the rear to the front.
Through this group study, we summarised that arthropod motion can be analysed through the body, limbs, coordination, and secondary motion. In reality, insect movement can be very fast, complex, and chaotic, so in animation we need to simplify the timing, enhance rhythm, and exaggerate body motion when necessary to make the movement clearer and more readable.
During the class presentations, I also learned a lot from other groups, such as the movement of birds, bears, and rabbits. Different animals have different body weights, skeleton structures, and movement rhythms. This made me realise that creature animation should be based on observation and analysis, rather than imagination alone.
