One Australian katydid has capitalized on its auditory prowess to capture prey in a very devious way: It lures male cicadas within striking distance by mimicking the female part of the cicada mating duet -a trick requiring it to recognize complex patterns of sound and precisely when to chip in. Awesome? Absolutely. Unexpected:That, too. I'd never given much thought to insect ears until now. But of the 30 major insect orders, nine (at last count) include some that hear, and hearing has evolved more than once in some orders-at least six times among butterflies and moths. [64] There are ears on antennae (mosquitoes and fruit flies), forelegs (crickets and katydids), wings (lacewings), abdomen (cicadas grasshoppers, and locusts) and on what passes for a "neck" (parasitic flies). [65] I know that this anywhere-goes approach may seem a little weird, but there's a simple explanation, In every case where an insect ear evolved, the starting point was an existing sensory organ: a stretch detector that monitors tiny vibrations when neighboring body segments move. Those detectors occur throughout the insect body but evolution typically only modified a single pair -apparently, almost any pair -to perceive the airborne vibrations generated by sound From there on, each new attempt to forge ears went even further in [66] their own direction as other structures were co-opted and reconfigured to capture, amplify,and filter sound, extract the relevant information, and convey it to the nervous system In mosquitoes and fruit flies, sound causes fine antennal hairs to quiver Most other hearing insects [67] have had "eardrums'thin, membranous patches of exoskeleton that vibrate when sound waves hit Katydid ears, as so neatly demonstrated by Montealegre -Z and his colleagues, are unique both in their complexity and th 51.

The author wants to add a sentence here to set up the rest of the paragraph. Which of the following would be the best sentence to add? A) While arachnids do not have ears, they do have sensitive leg hairs that allow them to process sound. B) But butterflies and moths are not the only insects that are capable of hearing. C) Not only can many insects hear,but many can also "smell "with their antennae D) Location is the most obvious
