hi everybody I have a new paper on uv signals in flowers and the perception of such signals by bees. Since that appeared in a journal that is probably rarely read by entomologists (Vision Research), I will announce it here. The reference is Chittka et al. (1994) Ultraviolet as a component of flower reflections, and the colour perception of Hymenoptera. Vision Research 34: 1489-1508. Please address reprint requests to Lars Chittka Ecology and Evolution State University of New York Stony Brook NY 11794-5245 USA And remember, the nicest stamps buy the nicest reprints !! Also, I have a question: I recently discovered an abstract in American Zoologist 32: 12a (1992) Ultraviolet reflectance of flowers and feeding behavior of nocturnal hawkmoths, by White, Stevenson, Haber (U Mass, Boston) and Haber (Missouri Bot Garden). Does anybody have the complete coordinates of these people?
