I’ve seen very few butterflies so far this spring. The cold and wet weathr won’t have helped, but it may be masking more serious problems.
This is the only one to date where I had a camera handy when it was around. A comma butterfly, very cooperative by resting on a birch tree, spreading its wings to warm up in the sun.
It had already been out for some time: there’s damage at the back of its right wing.
