“Something’s going on in early spring,” a professor said, and researchers are trying to solve the mystery.

Western monarch butterflies spend their winters in Pismo Beach and other sites on the central California coast. A few months later, they breed in the Central Valley and as far north and east as Idaho.
But where they go in between remains an open question.
Now, a group of researchers wants the public’s help to solve that mystery.
They would like anyone who spots a monarch north of Santa Barbara this spring to snap a quick picture. The researchers — from Washington State University, Tufts University, the nonprofit Xerces Society for Invertebrate Conservation, and the University of California, Santa Cruz — need photographic evidence, a date and a location to confirm where the monarchs might be living.
