The Miami blue has a wingspan of only 0.87 to a little over an inch. The wings, as its name says, are bright blue in the males, while they are gray with a bit of blue near the base in the females.

Zoo Miami is also a major partner, doing rescue missions to Montgomery that have collected more than 4,000 atala caterpillars and pupae this year, and nearly 6,000 in both 2022 and 2023.
