Third Instar 
Head height 2.5 mm. ; head width 2.8 to 3 mm. Head 
darker chocolate than preceding instar. Body length 18 mm. 
Darker chocolate. Processes brighter orange. Those on seg-

Each instar required from three to five days. The aver-

May 1 pupated May 21. The pupal stage lasted ten days. As 
food plant Aristolochia argyreoneuron was preferred, but 
the following species were eaten to a varying degree: A. 
ringens, A. forckelii, A. redicula , A. saccata , A. tag ala, A. 
fimbriata, A. brasiliensis , A. cymbifera, A. elegans, A. gigan-
