How can you hate a caterpillar and love a butterfly?
Some gardeners so love their passionflower vine (Passiflora) that they squirm at the thought of a caterpillar munching it down to nothing.
But that's what caterpillars do. The Gulf Fritillary butterfly (Agraulis vanillae) lays its eggs on its host plant, the passionflower vine, the eggs develop into larvae or caterpillars, and the caterpillars into Gulf Frits.
Our passionflower vine--which we planted specifically for the Gulf Frits--is now a skeleton. The caterpillars ate all the leaves, the flowers and the stems. What was once a flourishing green plant looks like a criss-cross of brown sticks.
Comedian George Carlin supposedly said "The caterpillar does all the work but the butterfly gets all the publicity."
And architect-author-designer-inventor Richard Buckminster Fuller observed: "There is nothing in a caterpillar that tells you it's going to be a butterfly."
And someone named John Grey offered this poetic comment:
"And what's a butterfly? At best,
He's but a caterpillar, at rest."
So, it is. Take a look at the Gulf Frit caterpillar and then check out the Gulf Frit butterfly.
Yes, a hungry caterpillar turned into a magnificent butterfly.

A lady beetle, aka ladybug, sharing stories with Gulf Fritillary caterpillars?
Well, not likely.
The lady beetle (family Coccinellidae) preys mainly on aphids--it can eat about 50 aphids a day or some 5000 aphids in its lifetime. But it will devour other soft-bodied insects, including mites, scales, mealybugs, leafhoppers, and butterfly eggs and larvae (caterpillars). Butterfly caterpillars move quite slowly; they are not Indy 500 speedsters.
We spotted a lady beetle early this morning on one of our passionflower (Passiflora) seed pods, surrounded by hungry Gulf Fritillary (Agraulis vanillae) caterpillars. It was somewhat like a two-peas-in-a-pod scene, but without the peas. Here were two insect species ON a pod, and both sharing the same warning color: red.
The Gulf Fritillary caterpillars are hungry. Very hungry. They've stripped the passionflower vine of all its leaves and are now eating the stems and seed pods. Actually, we planted the passionflower vine for them. But are they THAT hungry? They are. They're famished. And there are literally hundreds of them.
Sometimes we think that all of the Gulf Frit butterflies west of Mississippi are gravitating toward the plant to lay their eggs. The vine cannot support that many hungry caterpillars, despite predation by scrub jays and European paper wasps.
The lady beetle, we assume is not only eating the tiny yellow eggs of the Gulf Frit, but the tiniest of the tiny larvae. It's an exquisite buffet of tasty treats with high nutritional value.
And easy pickings.
