When the asteroid hit, most plant-eating bugs died

When a 6-mile-wide asteroid slammed into Earth 65 million years ago, it
wiped out the dinosaurs, about 80 percent of the world's plant species, and
all animals bigger than a cat.

But what happened to the bugs?

It's been tough for scientists to determine how the insects fared because
they rarely leave behind fossils.

But a Denver paleontologist and his Smithsonian Institution colleagues found
a way around the problem: By studying insect damage etched into thousands of
fossil leaves, they determined that many plant-eating bugs perished in the
big impact.
