Monday macrobug: backstroking grub

Posted by Callan Bentley

Here’s a close-up of today’s macrobug: Hard to tell what it is from this close in…

It’s a beetle grub of some kind.

Notice that it’s lying on its back, with its dorsal surface down and its ventral surface facing the sky.

This is actually the way this thing moves – rather than crawling, it undulates on its back, and moves forward (toward the head) that way. I see them crossing the road every so often.

I wonder: Why did the backstroking grub cross the road?

Ponder that on this lovely Monday!
