My kind of womb

This is a picture from the Dec. National Geographic and it is of brood cells that female Osmia avosetta bees make out of flower petals. As the article states, the bees "arrange flower petals to form unique nests that swathe their larvae in nutrients and warmth for the winter." Making one can take up to two days. So beautiful. This is almost as good as the Bowerbird article they had a few months ago (if you haven't read it you must!!! And check out the picture slideshow too....we now know where Goldsworthy and Daugherty get their ideas from).
