When we visited Rob's place recently we were all enthralled by the solar butterflies on a stick that flap their wings when the sun hits them. Rob is using them as a Cabbage White (moth and butterfly) deterrent with some success so far.
I went looking on eBay for something similar last night and found these non-solar butterflies on a stick for the most incredibly cheap prices delivered free to Australia. There are more expensive solar version available also if you go hunting, but I will stick with these little cheap ones for starters.
I searched for BUTTERFLY ON STICK.
