Characteristics: The largest butterfly occurring in the Larval food plant: Various citrus species, Rue. Distribution: Orsak (1977) listed this species only as "of possible Orange County Occurrence". He wrote: "A native of the southern states west to Texas and Arizona, it has been a California resident for only a little more than ten years. It is now commonly seen in the Imperial and San Joaquin Valleys (Emmel and Emrnel, 1973). The larvae, known as "orange dogs" to many Southerners, feed on a wide variety of Citrus in the United States. Papilio cresphontes may eventually spread to Orange County and become an established resident (and possible pest) on backyard and commercial Citrus." There are many recent sightings: 1997-98: 1999: 2004: 2005: 2006: 2007: 2008:
