Cybertronian butterfly

Cybertronian butterflies are some form of wildlife on Cybertron from the Armada portion of the Unicron Trilogy continuity family.

"Cybertronian butterflies" are roughly of the same size as butterflies on Earth, making them extremely tiny to Cybertronian understanding. They are also as colourful as their counterparts on Earth, but being made of metal are a bit more resilient.

Given the track record Transformers have on naming their planet's fauna, these creatures are probably called robotterflies or something equally creative.
