No fish do not eat Butterflies. Fish generally don’t attack butterflies in order to eat them, although they can bite them if they feel threatened by the colorful insects. The most common way that fish eat butterflies is by accident—butterflies can be caught in their mouths when the fish are trying to eat something else.
The type of butterfly that is at risk of being eaten by a fish depends on where the butterfly lives and how it moves through the environment.
Some kinds of butterflies live only in the ocean, but these are marine creatures known as “butterflyfish.” In contrast, terrestrial butterflies usually live most of their lives on land and only spend a short time flying over water. Most types of terrestrial butterflies don’t come into contact with fish as they fly over water.
On rare occasions, a terrestrial butterfly may end up in the water because it has been blown there by the wind or because it was attracted to something on the surface of the water (such as a flower floating there).
These butterflies have no ability to swim, so if they end up in the water, they will either drown or be eaten by fish if they are small enough for a fish to swallow.
Some types of fish are particularly attracted to color and may attack a butterfly just because it’s bright and colorful. This can be especially true of smaller species of fish — some species of bass have been known to attack brightly colored lures specifically because they’re fooled into thinking that they’re prey.
Do fish eat dead butterflies?
The short answer to your question is No, fish do not eat dead butterflies. As we all know, dead animals decay and break down into their constituent parts. Other organisms will consume these dead butterfly parts in nature.
But are they tasty enough for a fish to want to gobble them up? The verdict is still out on that one. We don’t have any definitive studies proving that fish would prefer butterflies over other foods they find in their environments.
A few researchers from the University of New Mexico saw an opossum eating a Monarch butterfly in 2013, so that is one example of a non-fishy animal eating a butterfly carcass. Other organisms that might benefit from the nutrients in a dead butterfly include ants, spiders, and beetles. While it is possible that some fish might eat a dead butterfly, there is no scientific evidence for that today.
Fish do not eat butterflies. Fish go around looking for food and will adapt to catch a wide variety of food choices. This is why it is possible for some fish to eat things such as plants, algae, insects, and small fish.
