Agave attenuata

agave attenuatabees in agave attenuataAgave attenuata is native to Mexico, but is commonly seen in Hawaii. It’s also known as lion’s tail agave, swan’s neck agave, or fox tail agave. 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.

White-lined sphinx moth caterpillar

This handsome fellow is the caterpillar of a white-lined sphinx moth (Hyles lineata). This caterpillar’s color can vary quite a bit. The markings on this predominantly black caterpillar can be green or orange, but the main color can be bright green or yellowish with black markings or red dots.

One consistent feature of these caterpillars is the orange horn on their back ends. This is also a good way to distinguish front and back. The horn looks like it could sting, but it can’t. It’s probably more of a visual deterrent to would-be predators.

The adult moth (below) has more uniform coloration. These moths and caterpillars are quite common but I rarely see then. This isn’t surprising considering how the adult moth blends in, but the caterpillar is quite striking and I’m surprised I haven’t seen more of them.

Grasshopper at Lapakahi

Grasshopper at Lapakahi

Grasshopper LapakahiSeveral weeks ago, when the Big Island had a couple of hurricanes in the vicinity, we were inundated with rain. Tired of staying indoors or slogging through mud, I headed down the road a few miles, to the dry side of the island, in the hopes of finding somewhere I could go for a walk.

I stopped at Lapakahi State Park, which holds the remains of an ancient Hawaii fishing village. It was dry and warm, though the trails there were still slick with moisture and closed to the public.

While I soaked up the warmth, I noticed this grasshopper (Schistocerca nitens I think) on a plant. It was hanging onto the stem and, despite my presence, seemed not in any hurry to move. It took me a while to realize there was something odd about it, but eventually I noticed that it was missing one of its hind legs. It’s not the first grasshopper I’ve seen in this condition and I always wonder how it affects them. The hind legs are the ones that launch them, so if they’re missing one do they ping off to one side? Do they end up going in circles? Or are they able to compensate?

I didn’t find out on this day as the grasshopper remained in roughly the same position the whole time I was there. Eventually I gave up watching and headed back into the gloom.

A praying mantis peers down

Praying Mantis staring

I posted recently (here) about finding the exoskeleton of a praying mantis after it had molted. It’s possible the mantis in this photo is the one that shed that skin, since I saw it in the same vicinity.

This mantis was stationed where a wall meets a ceiling and it was staring straight down that wall at me. I like this photo because I think it captures the mantis’s rather piercing stare.

A couple of days before I took this photo, another mantis, slightly bigger than this one, was perched on a Pepsi machine in the same vicinity. It was watching me as I went back and forth. Eventually, when I paused, it leapt onto my head. I reached up and encouraged it onto my hand, where it paused a moment before scampering up my arm. So I interposed my other hand, which it duly climbed onto. Cue the mantis then scampering up that arm. We did this little dance a few times before I managed to maneuver the mantis onto a deck rail. It perched there a while and then eventually flew off.

I guess I’m in a praying mantis purple patch.
