I think it's really cool how it curls up when not in use then unravels when they want to drink their food.
here are a few more butterfly shots (I got so many it was hard to narrow it down :))
This one was my favourite butterfly... the Blue Morpho. It is shimmery blue on the backside of it's wings but you can only see it when it's flying (it closes it's wings up when it lands)
If you would like to play along, next week's theme is "Colours"
