a most unusual birthday present


Last Friday evening, at the birdfest evaluation meeting, Lydia gave me a belated birthday present.

At first I thought she was giving me a cutting of an ivory plant, but the real present was 2 caterpillars happily munching away at the leaves!

Pretty, yellow-black-and-white (almost pale blue) caterpillars! 

In fact one of them was getting ready to metamorphose (is that the word?) into a chrysalis, its mouthparts were glued to the vein of one leaf, and it was hanging on, its small body curled up.

Lydia took them from her very own butterfly-friendly garden in the middle of busy San Juan.  With care and luck, they will turn into beautiful orange butterflies, Philippine cousins of the popular monarch butterflies of the Americas.

It's funny how the caterpillars caught everyone's attention, especially when Sean shouted "nagpalit na sya!" and the meeting was brought to a halt as everyone admired the shiny green chrysalis that the curled up caterpillar turned into. The perfect natural history lesson.
Thanks Lydia for a most unusual birthday present.  I'm so happy you thought of me as someone who would enjoy watching a caterpillar turn into a butterfly.  I'm excited to report that both of them are now in the process of change (as i said to Adri, a good lesson in apoptosis and molecular development!), a yellow chrysalis and a younger green chrysalis with a line of black and gold flecks.

Abangan ang susunod na kabanata...

  6. its called ivory plant or sometimes estrella del norte (calotropis gigantea). it's easy to propogate by cuttings (see http://katrinket.multiply.com/photos/album/34/in_my_mothers_garden_part_2#59 for picture)

  8. The plant is so common. Remember guys, this is the larval host, not nectar plant for the adult (butterfly). In a butterfly garden or habitat, there are always two food sources- leaves or buds for the larva and nectar from blooms for the adult. Butterflies need plants to survive. That is why the care of the habitat is so important. Moths spin silk to make a cocoon. A butterfly magically transform from a caterpillar to a chrysallis or pupa. The old is gone, the new has come. Inside the pupa is liquid. The amazing transformation happens inside. Watch out for Trinket's next episode of The Birthday Butterfly.
