By the size of it, it has been there a couple of days yet I hadn't earlier spotted it.
It is now settled on a swan plant, inside the safety of the caterpillar castle, so hopefully it will grow and flourish.
Meanwhile none of the eggs I brought inside, 2 days ago, are showing any signs of hatching.
When Monarch eggs are laid it can take about 6 days for them to hatch, when its later in the season like this and the weather is cooler.
This little caterpillar in the picture here seems fine, although it seems a little sluggish because we have a cooler day today. Hopefully it will grow to be a lovely fat caterpillar.
Time will tell.
