Lemon Migrant Butterfly

My most recent photography quest is to capture a butterfly.
Those gorgeous little fluttery things fly so fast though!
I haven't been able to snap one in flight.
And they never seem to stop.
So when this one flew past yesterday, and I said, "Just sit down, will you?", and it did, I couldn't believe my luck!

It's not great, I'm still on the hunt for a better photo.
But I do quite like this one.

After a little Googling, I believe this butterfly is called a Lemon Migrant Butterfly.
