G. rhamni doesn't like green iphones

[timmsyrj]

Not really a collecting report as such, but useful to anyone wanting to collect Brimstone (G. rhamni) males, I have spent the day fishing and having males of the Brimstone butterfly keep coming down and attacking my iPhone 5C ( the green one ) one even attacked one of the bite indicator bobbins which is fluorescent yellow, I didn't realise they where this territorial, behind me was a large alder buckthorn bush which they constantly flew around and came down to my upside down iPhone next to me.
Think I might have to get a blue case to see if there are any Purple emperor around.
