A Case of Mistaken Identity?

What kind of butterfly do you think the New Jersey observer saw? Which field marks helped you most in deciding whether or not this was a monarch?

Here’s the field mark that cautioned us that she had not seen a monarch: "Its antennae had a bright yellow dot on it."

Do you think the butterfly pictured above is the one that she saw? Compare it to the verbal description. Also compare it to the monarch.
