Monarch Butterfly Caterpillars

I mentioned the other day that we try to manage our ranch in a way that supports wildlife.  Today, I found a great example of that.  Monarch butterflies.

I took the grand kids on a hike this morning and we discovered that the Monarch caterpillars are in full swing devouring the milkweeds that we deliberately allow to grow in certain areas of the ranch.  They can only thrive in grassland.

Here are some photos of the caterpillars.  Can you spot them?  We only saw one Monarch butterfly in the air and I was unable to get a photo of it.
