This butterfly is very aptly named as long as its wings are open. It is an Orange Tip, but with its wings closed it is very well camouflaged, and can be very hard to spot. If you look closely at the back of the wings, you might just be able to see the orange colour bleeding through the wing.
If you wish to see the orange, there is another shot of this butterfly in my other album today.
Beautiful capture! I saw my first one this year yesterday. Spring Watch want people to report their first sightings of this butterfly to see how spring is coming on all over the country. Fav!
