Flies from South Texas to Argentina
Fruit and dung feaster as adult. Often seen puddling in mud. One of as many as 9 Hamadryas butterflies South of the border of Texas. (in general Crackers are also called Calicos) Species in this genus are called Crackers because of the noise the males make in flight.
Caterpillar host include vines (Dalechampia) and herbs (Tragia) in the family Euphorbiaceae.

Over the past couple of years these have become somewhat more common in south Texas. We've seen some very fresh individuals which leads up to believe they are perhaps breeding here. As far as I know there isn't any dalechampia growing in south Texas but we do have lots of native tragia.
These show up fairly quickly when butterfly brew is set out. Last weekend when I set out some of it we counted five Gray Crackers either feeding at various bait stations or perched on nearby trees at our local NABA park in Mission , Texas.
