Hi Doug & All, Apr 16, 2014
Reader beware is a good rule of thumb for all printed material. Mistakes
can be invisible throughout a long process of review and editing, or slip in
during proof 'correction' and no account which anyone will read can cover
all aspects in detail.
National Geographic has had a few bloopers over the years. One that
comes to mind, in an article about some Middle Eastern country ~1975, was
calling a one-horse cultivator (identical to those made in Michigan ~1940)
an ancient plow or words to that effect.
I gather from this article that Davis found, in rearing studies, that
insects which eat less well grow less, which is about as astonishing as
showing that there may be germs on the surfaces of money, so naturally NG
had to throw in some background and general interest content.
No mention is made of overwintering in California but other than that I
don't know how the passage that you singled out is misleading. Is only the
trip north multigenerational ?
