"Fieldnotes," October 27th & 28th, 2013: "Halloween," by Lynn Tennefoss & Caroline Kurtz (read by Allison de Jong). http://www.montananaturalist.org/
"Halloween is almost here, the time of year when ghosts and goblins, princesses and pirates show up in classrooms and workplaces. But the natural world also provides lots of great costume ideas. Birds, insects, amphibians, and coral reef fish are some of the most colorful creatures I can think of. The yellow and black stripes of a yellowjacket; wild riot of color on a Painted Lady butterfly; or the spots, spines and fins of a fish are all available to the creative Halloween reveler."
