Diagnosis. Distinguished from A. perplexus  by the usually darker, mottled fuscous and white ground color and fuscous lateral patches on abdominal segments A4 and A5. Male genitalia with a small circular sclerotized disc protruding from the ventral margin of the right valve near the apex which can often be seen without dissecting specimens ( Fig. 36aView Figures 33–36).

Life history. In the USA, larvae feed on the leaves of several genera of composites including Ambrosia  L., Borrichia Adans.  , Helianthus  L., Melanthera Rohr  , Pluchea Cass.  , Rudbeckia  L., and Xanthium  L. ( Matthews and Lott 2005). In The Bahamas, larvae were found feeding on the upper surface of leaves of Melanthera aspera (Jacq.) Small  , Wedalia bahamensis (Britt.) O.E. Schulz  , and Neurolaena lobata  (L.) R.Br. ex Cass. Larvae have the peculiar habit of chewing out a resting groove, usually along a leaf midvein, from which the larva stretches out to feed on surrounding leaf tissue or makes forays to other parts of the leaf, then returns when not feeding ( Fig. 67, 68View Figures 66–71). These grooves are visible on leaves many weeks after larvae have matured and moved to another leaf to pupate. Larvae were most commonly found on N. lobata  ( Fig. 66View Figures 66–71). Usually only one larva is found on a leaf. In rare cases, several larvae may be found on the same leaf, also favoring the midvein ( Fig. 67View Figures 66–71). Pupation occurs on the hostplants with the larval skin usually adhering to silk near the tip of the abdomen ( Fig. 70, 71View Figures 66–71). Adults come to light and may also be found perching in the vicinity of the hosts ( Fig. 69View Figures 66–71).

Distribution. This species is known from Bermuda, the Dominican Republic, Ecuador, Mexico, Puerto Rico, USA, and the Virgin Islands. It was not previously recorded in The Bahamas, and has now been collected on Abaco, Eleuthera, Grand Bahama, Long, and San Salvador Islands.
