Entomology is so interesting, as it is the scientific study of insects.
Oh that is cool.
I know, it is also a branch of zoology. 
Yea makes sense just more specific.
It was different back in the day too because the term insect was more vague back in the day.
Oh yea science is changing all the time.
I know, since entomology used to also include the study of terrestrial animals.
I might take a college course on it sometime.
You should learn about when it used to include stuff like snails, slugs, and earthworms too.
