Moths Mimic Sounds To Survive:
In response to the sonar that bats use to locate prey, the tiger moths make ultrasonic clicks of their own. They broadcast the clicks from a paired set of structures called "tymbals." Many species of tiger moth use the tymbals to make specific sounds that warn the bat of their bad taste. Other species make sounds that closely mimic those high-frequency sounds.
Fire Ants Are Emerging Nuisance For Virginia Residents:
Red imported fire ants (RIFAs), which have caused trouble in Florida and Texas for decades, are now advancing in Virginia. Colonies of the tiny, highly aggressive insects have been observed in the commonwealth since 1989 and, in recent years, have caught the attention of Virginia Tech scientists who are trying to learn more about the increasing number of fire ant infestations.
Some Forest Birds Can Survive In Agricultural Countryside With Limited Habitat Conservation:
Some tropical forest birds can survive alongside humans if given a helping hand, according to a recent study by Cagan H. Sekercioglu, senior scientist at the Stanford University Center for Conservation Biology.

RE: Moths Mimic Sounds to Survive.
Mimicking other species for the purpose of avoiding predators using visual, aural, or olfactory cues is a typical strategy that works for nature. In a way, each one is a form of camouflage. But it can also work the other way around when predators mimic harmless creatures as bait to get food. One example is the snapping turtle which has a wormlike tongue it wiggles to attract fish while keeping as still as a rock.. and then it snaps!
