Nobody really bats an eye when a chicken lays an egg. That's what we expect them to do.
But when a butterfly lays an egg, that's a different story--especially in December.
Gulf Fritillary butterflies or passion butterflies (Agraulis vanillae) head for the nearest Passiflora, their host plant, and lay their eggs, tiny little yellow eggs about the size of a sesame seed.
It's done so quietly and so effortlessly--and it's such a miracle--that you expect to hear Vivaldi's Spring or the sound of trumpets or loud applause or a standing ovation. Something.
But no, the female butterfly goes about her business of laying eggs, deftly avoiding mate-seeking males that attempt to draw her attention.
The egg will hatch into a larva or caterpillar, and the caterpillar will morph into a munching machine, devouring every leaf in sight. Then comes the chrysalis, and an adult butterfly emerges.
That itself, in the dead of winter, warrants Vivaldi's Spring!
