Last week was great for butterfly lovers. The sunny weather brought many summer specialities out onto wing.
Daintily searching through southern Britain's meadows for nectar, marbled whites are one in particular people look out for in July.
I was lucky enough to see some myself this weekend. Admittedly none perched quite like the one in this image from Ernie Janes, but was still a good sight.
If the sun comes out again this week, why not have a look for one yourself?
This is one of thousands of images from RSPB Images - our online photo library. It's recently had a makeover, so if it does rain this week, why not get your wildlife fix from there?
