The first one that was at the lower part of the porch window frame had changed and you could see through the outer shell the darker veining in between the areas of the orange on the wings and some of the white markings.

The second chrysalis, which is on the corner of the upper window on the porch, hasn't started to change colour and probably won't emerge today, perhaps sometime tomorrow.
I will just have to be patient.
In the meantime I thought I would work on this painting that I had started a few years ago (see posts on 13 September 2015 and 26 February 2018).

With a pale mixture of burnt sienna and French ultramarine blue I put in the furthest back tree trunks on the far shore and gradually darkened the colour and increased the size of the tree trunks as the trees came closer to the river.
Darkening the colour more I put in the largest tree trunk on the shore in the foreground.
Next I mixed a pale green of raw sienna, French ultramarine blue and Antwerp blue and using a sponge I put the leaves on the furthest back trees first. Then I slightly darkened the green mix and put in each layer of trees on the far shore.

I wet the river with clear water and using the green brushed in the reflections of the closer trees into the water.
While the river was drying I darkened the green mix and with the sponge I put the leaves on the foreground tree.
Lastly, I painted in the grasses and the growies at the base of the foreground tree and on the closer shore.
