I've seen this reported by Michael Levin, too. For example, Forms of life, forms of mind

Now what has been shown is that you can train a caterpillar to eat leaves on a particular color background. And then when you test the resulting butterfly or moth, they will go to that background to look for food. So, the memory persists, even though the brain is basically completely taken apart, dissolved – most of the cells die. Now you might think that this is a question about how to keep a memory when the medium is refactored? That’s step one, but it’s not even the exciting part here. The most exciting part that people never talk about is the following. Butterflies don’t eat the same stuff that caterpillars eat. Butterflies don’t care about leaves. They drink nectar.

Pretty amazing, really. The brain is dissolved in metamorphosis, but the memories persist and get adapted for the new configuration.

A similar result that he reports is that he can get an eye to grow on a tadpole's tail - and it can see (sometimes without even building a connection to the nervous system).

Then, when the tadpole turns into a frog, the eye is retained, even though the tail disappears.
