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.

Red Admiral butterfly

The Red Admiral butterfly is a European native that arrived in Hawaii in the late 1800s. Despite the longevity of its time in Hawaii, it’s a butterfly that isn’t seen a lot. This is the first one I’ve seen in six plus years here. I was on my way to go snorkeling when I noticed it and, of course, I was immediately distracted and snapped a couple of photos before it disappeared from view.

Variable and seven-spotted ladybugs

When I took this photo, I thought it was of two variable ladybugs mating. However, when I processed the photo, I noticed that the lower ladybug didn’t look the same as the top one. I think, instead, it’s a seven-spotted ladybug. I also noticed that that top ladybug is climbing up the side of the other one, which is not the usual mating approach.

So now I don’t know what’s going on. It could be that the top ladybug is trying to mate and has just got things seriously wrong. Or it could be a ladybug traffic accident, with the one bug getting in the way of the other. Perhaps they’re fighting. I guess I’ll never know.

Agave attenuata

These names stem from its long flower stalk which rises from the center of the leaves and arches over. Most agaves bloom and die, but agave attenuata blooms annually without dying. Also, unlike many other agaves, agave attenuata leaves don’t have leaves with sharp points or spiky edges.

The progression of the flowering process can be seen on one agave attenuata plant. In the second photo, starting at the base of the flowering stalk, there is a bare section where the flowering process has finished. Above that is a brownish section where small brown pods have been set. Some of these, that remain attached to the stem, will turn into green fruits. Near the end is the portion of the stalk that is currently flowering and at the end are buds that have yet to flower.

I was drawn to these plants, not just because of their striking flower stalks, but because in the mornings, bees were all over the plant. The top photo shows a bee clambering through a tangle of stamens and pistils. In the third photo, there were lots of bees working along the flowering portion of the inflorescence. Below, sometimes it’s hard work getting to grips with the task in hand.
