Giant Swallowtail - Papilio cresphontes
A Western Giant Swallowtail sipping at butterfly bush in my backyard garden. These can be difficult to photograph dorsally because when they nectar they tend to beat their wings continually. June 8, 2009.
Giant Swallowtail - Papilio cresphontes
Heraclides rumiko, formerly Papilio cresphontes, the Western Giant Swallowtail, also nectaring in my garden in Long Beach, where they can be common. I have a few citrus trees that they have oviposited on, but so far nothing has gone through to adult as far as I know. May 29, 2006. Rumiko was distinguished from cresphontes in 2014 by Kojiro Shiraiwa and Nick Grishin.
Giant Swallowtail - Papilio cresphontes ova or butterfly egg
I found a couple of cresphontes eggs on fresh shoots on my backyard orange tree on November 3, 2012. Haven't had any luck with this species in the past beyond first instars, but maybe this year will be different.
Giant Swallowtail - Papilio cresphontes larva
A week after finding the eggs, a tiny larva emerges. Note the remains of the egg in the background. I found two larvae on the tree. November 10, 2012.
Giant Swallowtail - Papilio cresphontes larva
A couple of weeks later, one of the caterpillars is gone, but the other is doing well. This is either a second or third instar. November 26, 2012. Obviously the resemblance to bird poop is a way of dissuading or fooling predators. Ah, the beauty of nature!
Giant Swallowtail - Papilio cresphontes larva
I found another larva in the same tree, and this one was bigger (prob. 4th instar). December 3, 2012.
