Thanks Michael
photolady has a good point, I often have to back up to avoid my shadow spooking insects when trying to get close, spooks them every time, especilloy early in the AM. First thing in the morning they find a sunny spot and sit there to warm up. Your shadow removes that sunlight so they go to another sunny spot. Especially butterflies. They have to have a body temp of at least 85° F to fly, so if you see one with perched wings open in the morning it's trying to warm up. Once warmed, it will fly away every time. Not sure about body temp requirements for other insects, but they will all fly away if your shadow crosses them. The shadow also draws their attention.

This is an older one, just started going through the FLickr shots and finding some of the older ones.
A small green bee that is not easy to get at all, the move fast and a lot...
And a lizard. They don't often let me get close enough for macro shots, but this guy sat still for me
