Sheet Music

A bridge and a stream. What more could Organ Pipe Mud-dauber Wasps (Trypoxylon politum) need than shelter from the rain and a source of their building material?

Well, spiders, of course. These wasps paralyze spiders to feed their young inside these mud-nests. Here’s an interesting observation: Tufted Titmouse and Downy Woodpeckers breaking into these to get the larval wasps. And also the spiders?

I don’t seem to have a photograph of one of these wasps. I’ve sure seen a similar species, the Black and Yellow Mud-daubers (Sceliphron caementarium). They’re particularly photogenic, or just hang around long enough for photographs. They also feed their young spiders.

Well, if you think I’m a worse case scenario-ist, read this on the effects of the return to Miocene-level global temperatures for the centuries to come. We’re remaking the planet like it was 16 million years ago!
