Surprise

I'm surprised the Brimstone tolerated such intrusions on its delicate wings. Perhaps the need to feed after the cold and wet spell took precedent.

Intrusion

Yes, I was surprised by this and cannot remember seeing it happen before. I missed the photo when three flies were on the butterfly, unfortunately. The butterfly was not especially slow, either, as it was flying away and then returning again. Yet, it seemed not to mind the intrusion and let the flies stay there for quite long periods.
