So what do you think about Entomology..The study of insects.
I think insects are gross, but I am glad there are people that study them.
As do I actually.  Entomology is actually a branch of zoology
What kinds of things do they study about insects?
a diverse group of topics actually including molecular genetics, behavior, biomechanics, biochemistry, systematics, physiology, and devolopmental biology
Do they study them in nature and in a lab?
yes they do and at some 1.3 million species, insects account for more than two-thirds of all known organisms
That sounds so gross that there are so many creepy crawlers.
