Variable and seven-spotted ladybugs

variable and 7-spotted lady beetle

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

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.
