Announcing the Release of
Mariposa Road:
The First Butterfly Big Year
by Robert M. Pyle
Read all about Bob Pyle's epic cross-country butterfly adventure!  
Robert M. Pyle, the noted lepidopterist, writer, and Xerces Society founder, spent 2008 on an historic journey. Racing against the calendar, Bob crisscrossed the United States to find, experience, and identify as many of the country's eight hundred species of butterflies as he could. Bob's new release, Mariposa Road: The First Butterfly Big Year, recounts his immense undertaking.
book coverAs the publisher says, "At turns whimsical, witty, informative, and inspirational, Mariposa Road is an extraordinary journey of discovery that leads the reader even farther into butterfly country and deeper into the heart of the naturalist."

We would add that Mariposa Road is Bob at his best. He combines natural history with personal observations to weave an entrancing tale. This is a must read.

Thank you to everyone who pledged or donated to the Butterfly-a-thon!
Leona's little blueAs Bob traversed the U.S. in search of butterflies, many of you generously contributed to the Butterfly-a-thon fundraiser. Thanks to your pledges of 5 cents, 10 cents, or even a dollar for each of the 488 butterfly species that Bob saw Xerces raised over $40,000!

This money is being used for conservation of threatened and endangered butterfly species. The Butterfly-a-thon pledges have enabled us to:
  • develop land management plans for the Bureau of Land Management to conserve the imperiled mardon skipper; as a result, the BLM is reducing many of the threats this butterfly faces;
  • assist landowners, the Farm Service Agency, and the Natural Resources Conservation Service in restoring habitat for the endangered Karner blue butterfly in Wisconsin;
  • file Endangered Species Act petitions seeking federal protection for Leona's little blue, the bay skipper, and the sand verbena moth and their habitats;
  • launch a project to evaluate the status of monarch overwintering sites on the California coast and provide tools to citizens and land managers to protect those critical areas; and
  • initiate a project to work with the USDA's Natural Resources Conservation Service and native seed producers to develop locally native species of milkweed for monarch conservation in southern U.S. states.
Butterfly-a-thon money also supports work that has led to the appointment of Scott Hoffman Black, Xerces executive director, as chair of the International Union for Conservation of Nature's Butterfly Specialist Group. Bob Pyle was the first chair of the IUCN's Butterfly Specialist Group in the 1970s.

These are just a few of our butterfly projects that have benefited from Butterfly-a-thon pledges. We will continue to advocate for the protection of many other rare, threatened, and often overlooked species of butterflies and their habitats.
