"Favorite Plants of the Western Cascade Butterflies," with Tanya Harvey.
On Monday April 2, the Eugene Springfield chapter of the North American Butterfly Association is pleased to present
Tanya Harvey, naturalist, artist, photographer, and plant and butterfly enthusiast in a presentation entitled:
Favorite Plants of the Western Cascade Butterflies.
Butterflies are very closely tied to plants, both for food for the caterpillars, and nectar for adult butterflies.
Many species have a limited number of host plants, sometimes only one, that they can feed on. Unlike the distant
traveling of monarchs, many butterflies don't stray far from their plants.
To find butterflies, it can be very helpful to know how identify their host plants and favorite nectar flowers.
Join us for beautiful photographs and clues to finding those special butterflies in the Cascades when Tanya Harvey
introduces us to the Favorite Plants of Western Cascade Butterflies.
Her April 2 talk will be excellent preparation for the joyous return of warmth and the long sunny days loved
by butterflies. We can start to plan for the special spring/summer trips which will be announced at the April 2 meeting.

"Butterflies on the Move: Monarchs, Mass Migrants, and Climate Change."
On Monday, October 22, Dr. Robert Michael Pyle, a world renowned environmentalist and butterfly specialist will
give a detailed look at the birdlike, annual migration of monarchs, and describe his own travels with monarchs that
resulted in his book Chasing Monarchs and a new model for the relationship between eastern and western
monarchs. He will also discuss Painted Ladies, California Tortoiseshells, Snouts, and other species that either
emigrate out of the South each year or experience population booms and busts with resultant locust-like mass
movements. All of these phenomena, and butterfly distributions in general, are showing effects from the changing
climate. What will global warming mean for our butterflies?

"What Good Are Bugs? The Case for Invertebrate Conservation."
Scott Hoffman Black is Executive Director of the Xerces Society,
the international organization dedicated to protecting biological diversity through
invertebrate conservation. As an ecologist and entomologist, he has extensive
experience in endangered species and native pollinator conservation. His topic will be:
What Good Are Bugs?
The Case for Invertebrate Conservation
- You can thank insect pollinators for one third of every mouthful of food that you
eat.
- Grizzly bears in the Rocky Mountains of Montana get over one quarter of their
yearly calories from eating moths.
- Without the lowliest flies in a stream for young fish to eat - your last grilled salmon
would have been impossible.
- In fact the direct benefit of insects to Americans has been calculated to be worth
more than $57 Billion a year.
With will over 1 million known species, insects and other invertebrates eclipse all other
forms of life on Earth. The ecological services of insects, such as pollination, are vital to life
on this planet. Though they are indisputably the most important creatures on earth, invertebrates
are often overlooked. Scott Hoffman Black will explain why we should be concerned with conserving
insect habitat and highlight important ways that each of us can better protect this valuable
resource.

"The Art of Function: The Function of Art."
Jeffrey Miller is working with Dave Janzen in Costa Rica where they are comprehensively investigating the
Moths and Butterflies in one large province of this biologically diverse country. The Janzen project
has trained Costa Rican workers to find caterpillars on host plants. The caterpillars and some leaves
of their host plant are brought to a breeding area where caterpillars emerge. In this way the project
has identified the complete cycle from host plant to butterfly or moth. Many new species are often
found in this manner. The photos of butterflies and moths will be spectacular and diverse.
Costa Rican Butterflies, Moths and Caterpillars are renowned for glorious colors and patterns. Beyond
their beauty these colors and patterns may be: conspicuous, warning colors as a special means of
defense, or cryptic-concealment through camouflage. Professor Miller will present photos of
caterpillars, moths and butterflies to illustrate the roles colors and patterns play in the Darwinian
contest of survival of the fittest.
Professor Miller is a specialist in insect ecology and biodiversity. With D. H. Janzen and W.
Hallwachs he has coauthored two books: 100 Butterflies and Moths: Portraits from the Tropical
Forests of Costa Rica, and 100 Caterpillars: Portraits from the Tropical forests of Costa Rica.

"Taylor's Checkerspot."
Paul Severns has been studying a rare butterfly, Taylor's Checkerspot, in the Corvallis area. He is
unraveling the complex current conditions at which this butterfly persists, in the effort to devise
strategies to prevent its extinction.
Taylor's Checkerspot is a Candidate Endangered species in the USA and is an Endangered Species in Canada.
It is restricted to remnant prairies bordering Oak and young Douglas fir forests. At different stages of
its life cycle it uses a number of host plants. In Oregon, exotic plant invasion, habitat loss, and
habitat degradation has conspired to yield a suite of human-modified conditions under which the current
populations now persist.
In this talk Paul will highlight the important interactions between exotic grasses, exotic and native
larval host plants, Taylor's Checkerspot own microevolution, oviposition choice, and habitat conditions
that are related to the butterfly's current survival and extinction. At the heart of Taylor's Checkerspot
conservation is a conflict between host plant evolution, exotic plant invasion, and our concept of "native"
habitat restoration. Come to hear potential ideas for conservation of Taylor's Checkerspot.
Paul M. Severns is a researcher of excellence, with years of experience in studying butterflies. He is
completing his doctorate in the Department of Botany and Plant Pathology, at Oregon State University. All
those of us who know Paul through his research in the wetlands, or in leading butterfly trips, or through
his previous lectures, etc. will not wish to miss his guaranteed to be enthusiastically interesting lecture.

"Into the Acarai Mountains of British Guyana: 21st century expeditions and the important role
of Natural History Collections."
This talk will center on an expedition taken by Entomologist, Christopher J. Marshall, to a remote region of British Guyana
near the border with Brazil. The expedition, a joint venture between National Geographic, the Smithsonian Institution and
Conservation International, included an international team of biologists seeking to document the biodiversity in this rarely
visited locale. It took over a year of logistical preparations and tens of thousands of dollars to make the trip possible.
In addition to introducing you to the breathtaking beauty and grueling hard work that are hand in hand with big expeditions
- this talk will highlight the increasing role and need for natural history collections, and the specimens therein, for
understanding Earth's biodiversity, especially insects. Some of the specimens and Guyanese paraphernalia from this
expedition, as well as additional specimens from the Oregon State Arthropod's extensive holdings will be on display for
attendees to view and discuss.

| April 5, 2010 | "Life
Histories of Cascadia Butterflies," with Professor David James of Washington State University at Yakima.
Entomologist David James and his colleague Dave Nunnallee have completed the rearing and life histories of 160 species of
Washington butterflies. This is a tremendous contribution to the study of NW butterflies which will be published by OSU press.
This is David James's report on his soon to be published book: LIfe Histories of Cascadia Butterflies.
While the PNW is well endowed with books describing the butterfly fauna of Cascadia (S. British Columbia, Washington,
Idaho and N. Oregon), all of these focus on identification and the ecology of adult butterflies. To date there has been
very little information published on identifying the immature stages of Cascadian butterflies, nor do we know very
much about the biology and ecology of Cascadia butterfly eggs, caterpillars and pupae. This will be remedied shortly
with the publication by Oregon State University Press of Life Histories of Cascadia Butterflies, by David James
and David Nunnallee.
His presentation will provide an overview of the forthcoming book which will be illustrated by nearly 1500 high quality
images of every stage (egg, all larval instars, pupa, adult) of virtually all of Cascadia's ~ 160 species. His presentation
will provide a selection of these images as well as new information on aspects of the biology and ecology of Cascadia
butterfly immature stages.

"Color Vision and Color Blindness in Admirals, Coppers, and Metalmarks," with Professor Gary Bernard
from the University of Washington.
Dr. Bernard will present a program based on his original research. The complex eyes of butterflies and what they see and
how they see it is the general topic. We will learn about the structure of the eye and the surprisingly many variations
possible in specific butterfly species. Some people are unable to tell red from black. So it is with some butterflies,
like the Viceroy. Other butterflies, like male Coppers, are red-blind only in the dorsal third of their eyes. The rest
of their eyes see red even brighter than people can see. Metalmarks are amazing. They can see way into the far red at
wavelengths where leaves are even brighter than in the green. The width of the Metalmark visible spectrum is greater
than that of people. Why? His lecture is guaranteed to dazzle you with unique observations.

"The Dangerous World of Butterflies," with Peter Laufer.
Dr. Laufer, winner of major awards for excellence in reporting, is an independent journalist, broadcaster and documentary
filmmaker working in traditional and new media. He is currently the James Wallace Chair in Journalism and Communication
at the University of Oregon. He will discuss his book The Dangerous World of Butterflies: The Startling Subculture of
Criminals, Collectors, and Conservationists, and will share with us "a true tale of beauty and obsession, smugglers, and
scientists" as he relates his journey into the subculture of butterflies.
Turning from the Iraq War, author and journalist Laufer (Mission Rejected: U.S. Soldiers Who Say No to Iraq) decided
to focus on the presumably innocuous business of butterflies. There, he found yet more violence, corruption, and unanswered
questions, resulting in another compelling all-angles examination. Fluttering across the globe for at least 40 million years,
Lepidoptera face increasing threats in modern times, largely from habitat loss and pesticides.
