Brimstone and Everlasting Pea

I've been doing more admin on my mother's behalf and for my aunt today, so I was glad to go for a short walk locally and potter in the garden. There are butterflies in profusion which is very pleasing. This female Brimstone was enjoying the flowers on the Everlasting Pea plant in my garden. I find this scrambling plant  becomes too invasive by late summer, but at least the insects like it.
