Wood white butterflies in Spain.

I took this photo with a small compact camera, which shows that you do not need expensive equipment to get close!  It was only later when processing the image that I noticed that the butterfly on the left appears to have raised a partly unfurled proboscis.  Was it offering the other one a drink?  No, these are courting butterflies. For a more detailed account see my later blog: Wood-whites go-a-courting!
