The Eastern Festoon occurs in warm, usually dry, places such as in dry grassland with scattered bushes, in scrub, near hedges, on agricultural land, vineyards and olive groves. It is also found in river valleys. Choosing plants growing near bushes or trees, the female lays her eggs mostly on Birthwort (Aristolochia clematitis), but also on other birthworts. The Eastern Festoon has one generation a year and passes the winter in the pupal stage.
