What do you call a bug-eating mammal?

There isn't one specific word for a bug-eating mammal. The most accurate term is insectivore.

However, "insectivore" can be a bit confusing, as it is also used as a taxonomic order (Insectivora) that includes animals like hedgehogs, shrews, and moles. These animals primarily eat insects, but their diet can also include other invertebrates and sometimes even small vertebrates.

Here are some other terms you might use, depending on the context:

* Bug eater: This is a simple and straightforward term that is easy to understand.

* Entomophagous: This is a more scientific term that means "insect-eating."

* Insectivorous: This adjective describes an animal that eats insects.

Ultimately, the best term to use will depend on the specific situation and what you want to emphasize.
