This feels familiar. Plus more caterpillar videos.
While walking to a popular Perth fishing spot, I noticed a long line of processionary caterpillars crossing the footpath so I got out the trusty Canon 5D and grabbed some time lapses of the little critters doing their thing. I was amazed how they followed the exact route that the front caterpillar was making as you can see while they scale the wall!
