Orange Tip Butterfly

I was sat in the hie on Wednesday and noticed lots of small white butterflies flying backwards and forwards not landing. I could see that they had a Orange marking on them so it new they were the Orange tip British Butterfly that arrives in April Mat time. They never stop to get a picture so i found a field where the odd one was landing and stood still for 10 mins and one landed close by. They fly off if anything moves towards them so i used the zoom lens to get the ID shot for the blog.
