Lemon Butterfly, Checkered Swallowtail

Very ornate swallowtail which flits from Africa, Madagascar, and Southern Saudi Arabia. Even though "called" a swallowtail, they do not actually sport "tails". Sexes are so similar it is difficult to tell apart except to actually witness the female ovipositing on larval host plant.

Their larval hosts include plants of the Rutaceae (or Citrus) Family

Not to mislead... I can not claim this species for my own zip code. My pictures are ones taken March 2008 while volunteering at an exotic butterfly exhibit at Botanical Gardens here in Fort Worth.
