Grizzly bears and moths

[Patricia & Jeff Harding]

According to James Fitzgerald, et al, in _Mammals of Colorado_, (1994)
"Young adult grizzlies are the most effective hunters.  The animals have
also been observed to work equally hard excavating talus slopes at high
elevations seeking adult miller moths (the same insects that appear in
large numbers at lower elevations many springs and summers during
migration)."  I believe his information comes from Steve and Marilyn
French.
