[Geology2] 50 million year old cricket and katydid fossils hint at the origins

50 million year old cricket and katydid fossils hint at the origins of
insect hearing PhysOrg.com [USA], January 3, 2012

How did insects get their hearing? A new study of 50 million
year-oldcricket and katydid fossils -- sporting some of the best
preservedfossil insect ears described to date -- help trace the
evolution ofthe insect ear, says a new study by researchers working at
the NationalEvolutionary Synthesis Center. Insects hear with help from
unusual ears,
said co-author Roy Plotnick of the University of Illinois at Chicago.
Grasshoppers have ears on their abdomens. Lacewings have ears on their
wings. The ears of the tachinid fly are tucked under the chin. "Insects
have ears on pretty much every part of their body except on their
headproper," Plotnick explained.
