Today saw the launch of Butterfly Conservation's Big Butterfly Count for another year. For the next month, in the UK, you can make a contribution to the conservation effort by submitting your sightings. I submit my records through the handy Big Butterfly Count app which is very easy to use.
Of course, today all I saw was this single Small White, but it was a bit overcast when I was looking around on campus this lunchtime. And they all count.
