Rolling, rolling, rolling, keep that …

Dung beetles prepare a dung ball prior to rolling it away.Dung beetles roll their dung ball down a steep hill.
I came across these industrious beetles about half way up a steep trail. They’re rolling dung beetles, as opposed to ‘tunnelers’ or ‘dwellers.’ Tunneling dung beetles dig a hole and bury their dung. Dwellers simply live in the dung where they find it. Rolling dung beetles make a ball, roll it away, and then bury it. In each case, the purpose of this activity is for the female to lay her eggs in the dung. When the egg hatches the larva will have its food source ready and waiting. Yum!

I’m glad my mother didn’t opt for this strategy, but dung beetles make such a valuable contribution in recycling this waste that they’re often introduced into areas to help in this process. And that’s not the only laudable quality they possess. According to livescience.com, dung beetles can also navigate using the Milky Way, the only non-human creatures known to do so.

I have to say, I was a little worried about how these two would get on on this steep hill. They weren’t around when I returned.

Passion vine butterfly caterpillar

I took some photos of a passion vine butterfly flitting around a hedge and when I looked at them at home I noticed a distinctive caterpillar in the background. So next day, I returned, hoping it might still be there. Not to worry. The hedge was literally crawling with them. That’s when I noticed the passion vine twining through the hedge.

The spines and orange and black coloring are nature’s way of saying ‘watch out.’ This caterpillar is poisonous if eaten, not that I was tempted. They also have a voracious appetite and can defoliate a plant, especially a young one. Certainly, the ones I watched munched their way through leaves with great thoroughness.

Ash grey lady beetle

I’ve always thought of lady beetles as little red creatures with black dots on their backs. So I was enlightened to see this one, also known as the ashy grey lady beetle (Olla v-nigrum). Apparently, this species can also have a completely different coloring. I learn something every day!
