Chewed flower

Dendrobium loddegesii - my first photo with the new camera, the Canon EOS digital. Something ate one of the flowers!
This is a species from China and Vietnam. It's actually pinker than this photo suggests. I took this in full sun. The flowers are quite large considering the plant and the leaves are very small and compact. The flowers are about 2-3 cm across! I find I can get closer with the standard lens and the auto focus on this camera than I can on the old Canon 35mm. I don't really want to buy that macro lens....
