Hi, I get the mistakes with the verb "help" and the pronoun mistake at the end of the underline portion. Did it matter whether the modifier that described the insect eye started with "having" or "with"?

Thank you.

The answer is no-- it doesn't make a difference. "Having hundreds of eyes" and "with its hundreds of eyes" mean the same thing, are both grammatically correct, and are both an equally good "fit" for the sentence. I'm glad you asked about this, though. This is an excellent example of a GMAT SC distractor. To challenge test-takers, he GMAT loves to present structures that look significantly different, but are actually both correct.
