Euthalia aconthea can be found in forests, urban areas, wastelands or agricultural land where there are host plants.
   Euthalia aconthea fly at high speed, with a flying style that is a rather stiff flap and glide style, with wings barely going beneath horizontal.
   Males fly at low altitudes to patrol and defend their territory.
   They are often seen basking during the day with wings opened flat, or visiting flowers and ripe fruit, either on the tree or on the ground.
   They have dark brown dorsal side wings with wide, indistinct post-discal bands on both wings in males. The inner edges of the band are whitish in color, the wings give off a dark purple hue when viewed from the side.
   * As members of the Brush Footed (Nymphalidae) family, they use their pair of shorter frony legs for food tasting, and their two pairs of longer rear legs for propulsion.
