Monarchs slighted -- sorry!
Contrary to the report in SF#49, at least one tagged monarch butterfly has been found among the wintering colonies in Mexico. In early 1976, a tagged individual from Chaska, Minnesota, was indeed found among a huge cluster in Mexico. Also, a few butterflies tagged in the northern states have turned up in Texas, well on their way to Mexico.

Comment. So, it seems that A.M. Wenner, the University of California researcher, will have to correct his records and perhaps modify his theory.
