How are the river valleys of

Monarch butterflies like these migrate 2,000 miles every

Thinking about the monarchs gave Lockwood and DeBrey
a new way to look at the locust mystery. Instead of
focusing on the swarming phases of the locust and trying
to explain the disappearance of trillions of locusts spread
over a vast area, they looked at the years between
outbreaks. Maps from the late 1800s pinpointed the
locations of the locusts' permanent breeding zones in the
river valleys of Wyoming and Montana. A much smaller
population of the insects had lived undisturbed in these
areas for thousands of years.
Both provide places for a type of insect
to live.
Both have been winter homes to
butterflies.
Both have been damaged by swarms
of locusts.
