Signs: Christa’s swing

I don’t know who Christa is or was, but there were a couple of things that struck me about this image.

The sign and the swing’s rope and seat were in excellent condition in stark contrast to the tree, which was dying and deliberately so. The channel around the trunk, below the sign, is intended to kill the tree, probably a silk oak, which can take over and crowd out native trees.

And then there’s the location, not far from the old quarry near the foot of Pu’u Wa’a Wa’a. It’s more than a mile down the hill to the nearest habitation, a ranch that runs livestock in this area. So, an isolated spot for Christa’s playground, but a wonderful location too, with views to the Pacific and surrounded by birds and animals, both domestic and wild.

Posted in response to this week’s Sunday Stills challenge on the theme of ‘Playground.’ See more responses here.

Passion vine butterfly on a passion flower

This passion vine butterfly was feeding on passion flowers, but it will feed on many other flowers, too. It gets its name because passion vines are the host plant for the passion vine butterfly’s caterpillar. Those caterpillars spend their days munching leaves, many of which have little yellow bumps on them. The bumps, which can be seen in the photos, are the plants’ way of trying to fool the butterflies into believing that there are already eggs on the leaves and so it’s not a good spot to lay more.

It’s hard to know how effective this ruse is. I’ve seen many butterflies laying eggs on these leaves, but perhaps some are discouraged. Regardless, the caterpillars will move from leaf to leaf while chowing down, but they never seem to defoliate the plant, which is, in any case, a robustly growing vine.
