The larvae of A. pagana and A. ochropus are quite similar, en aften occur together. Often, pagana larvae have an undivided black spot on the abdominal segment, while in ochropus this spot is divided in two. A fully reliable difference, according to Chevin, is that in pagana the black dots of the abdominal segments, seen from above, are arranged in neat length rows, while in ochropus they form much more untidy rows.
