There is still time to participate in one of the largest citizen science projects, the Big Butterfly Count 2019. You can log your butterfly sightings until 11th August, full details on the website.
Most of the usual suspects were present in the garden. There were at least four large white butterflies. New to my list was a gatekeeper, but I didn’t manage to get a photograph.
As well as nectar rich flowers for the butterflies it is also important to have the larval foodplants. You can find lots of good advice here.
