The Insect with Two Brains

October 1, 2025
00:00

A caterpillar and a moth have radically different brains tailored to their distinct life stages—caterpillars need brains for eating and crawling, while moths require larger brains for flight and mating behaviors. During metamorphosis, the caterpillar’s brain dissolves and is rebuilt ten times larger to control these new functions.

Guest (Male): Is there an insect with two brains? Find out on today's Creation Moments. And now, here's our Creation Moments host, Ian Taylor.

Ian Taylor: We've all looked in wonder at the amazing transformation of a caterpillar into a moth. However, did you realize that a moth needs an entirely different kind of brain than a caterpillar? We can truly say that here we have an insect with two brains.

In the caterpillar stage, the moth finds itself lumbering about in a body that is primarily designed for eating. Its brain must be able to command powerful jaws and a comparatively huge digestive system, as well as the complexities of caterpillar locomotion. The world of the caterpillar is very different from the world of the moth.

During metamorphosis, the caterpillar completely dissolves and the moth is rebuilt from the liquid. The brain, for example, requires new nerve cells, new connections between brain cells, while some brain cells change function, migrate to new locations, or even die.

The result is a brain that is ten times the size of the caterpillar's and ready to control flight. The moth's primary purpose in life is to reproduce, so its new brain is able to generate the odors used by moths to identify and communicate with potential mates. It is also equipped to detect the scents of potential mates.

Only our Almighty Creator could completely rebuild a caterpillar into a moth. Only He could rebuild and increase its brain tenfold in only a week or two. Even more amazing is how He remakes people. Through the forgiveness of sins in Jesus Christ, He turns us from people who wish to escape Him to new creatures who love Him and find joy in Him.
