White-tipped Cycadian Metamorphosis

For over a month I followed the transformation process of the beautiful White-tipped Cycadian (Eumaeus godartii). These butterflies are very common at Tranquilo Bay.  During this time, I measured and took pictures of these colorful caterpillars to record the progress in their development, from a little caterpillar, to the moment when they finally finish their metamorphosis and turn in to elegant butterflies.

The life cycle of this species is associated with a very primitive plant, the Zamia, that belongs to the Cycadales order. Cycads contain toxins that this type of butterfly probably uses as a chemical defense.

This caterpillar feeds exclusively on the plant where its eggs where laid and always stays in groups very close to each other.  They eat constantly and grow fast.  At the end of the caterpillar stage they secrete a silky white string that holds them underneath the leaves, where they turn into pupas and then the butterfly will emerge from it.
