yesterday i watched as this butterfly flitted around my garden, landing on the echinacea, resting for a while, then floating off to somewhere else. she returned many times - at least i think it was the same creature. finally she landed and stayed, and was still there as dusk fell. now this morning, she is there still, unmoving. i did not disturb her to take this photo but now i wonder: do butterflies sleep? or did she die yesterday as i looked on in fascination?
