the united states and brazil are home to a large number of katydid species, nocturnal insects related to grasshoppers and crickets.

Explanation:

The subject "The United States and Brazil" is a compound subject (two countries joined by "and"). In English grammar, a compound subject joined by "and" is plural. The verb "are" is the correct plural form of the verb "to be" (the base form is "be", present - tense forms: "am" (first - person singular), "is" (third - person singular), "are" (plural and second - person singular)). So, there is no subject - verb agreement error.

Answer:

The United States and Brazil are home to a large number of katydid species, nocturnal insects related to grasshoppers and crickets.
