The lucky aspect is that the orange sulphur butterfly normally has its wings closed whenever perched.
I occasionally wonder why yellow butterflies are called "sulphurs," but I suppose it makes sense in certain situations. For instance, calling a butterfly an orange yellow doesn't sound right.
Photo note:I used the Pentax K200D, with the SMC-A* 200mm macro lens (with the Pentax 2x multiplier), for the first photo, and the Pentax *1st D (but I forget which lens) for the second. Both were taken in July, but the first was in 2009 and the second in 2008.
