Odonata Updates
We have continued to update the information on Odonata
which we publish at the Black Range website, we have
published a second edition of the survey work, we have
published articles in this journal, and we have added
addenda to the second edition to the Odonata page on the
website. Thus far, addenda have been added for Eastern
Ringtail, Aztec Dancer, and Vivid Dancer (two: one on the
species and one on the research which led to including it in
our survey). See covers above.

the effect. The basic technique he used is well known in
the artistic world. Many painters, working in many
mediums, know how to achieve it - perhaps not as well, but
they know the concept. It all starts with a base level of
paint, generally a hue of white but even tans will work;
base levels in differing colors create differing effects. After
applying the base layer the artist paints her image on top
of it, and the light (in this case) hue of the base layer shines
through, creating a luminescent glow.
But, alas, this is a natural history journal not a work on art
history. Instead of Vermeer, letÕs discuss ÒHidden white and
black feather layers enhance plumage coloration in tanagers
and other songbirdsÓ (Rosalyn M. Price-Waldman et al.,
