Have you ever been interested in collecting bugs in jars?
Oh yes, I loved collecting grasshoppers when I was a Kid,. what about you? 
I always wanted one of those ant farms but never got around to getting one. Essentially, you practiced entomology as a kid by collecting those grasshoppers!
I don't know, as I understand entomology is the scientific study of insects
Correct! You studied the insects, so essentially you did some sort of science, even if it wasn't very scientific. What other bugs did you like as a child?
I liked ants but never had one of the farms either.  but I made homes for the grasshoppers, poor things
I'm not a fan of insects these days but I can respect their roles in our ecosystem. Do you save insects that enter buildings?
in which there is a focus on insect-related inquiries is, by definition, entomology. Entomology therefore overlaps with a cross-section of topics as diverse as molecular genetics, behavior, biomechanics, biochemistry, systematics, physiology, developmental biology, ecology, morphology, and paleontology.
At some 1.3 million described species, insects account for more than two-thirds of all known organisms, date back some 400 million years, and have many kinds of interactions with humans and other forms of life on earth.
History
"Plain Speaking", "But now we've got just this one evangelist, this Billy Graham, and he's gone off the beam. He's...well, I hadn't ought to say this, but he's one of those counterfeits I was telling you about. He claims he's a friend of all the presidents, but he was never a friend of mine when I was President. I just don't go for people like that. All he's interested in is getting his name in the paper.
