This population of crickets is experiencing rapid adaptive evolution in the wild unlike anything observed before. It's essential we glean as much insight from this rare opportunity as possible.
marywestwoodMore than a decade ago, scientists made an incredible discovery in the Hawaiian Islands.
Male crickets sing to attract females to mate, but lethal, eavesdropping parasitic flies also use this as a cue to locate hosts for their larvae. In an incredible display of rapid evolution, male Pacific field crickets in the Hawaiian Islands lost the ability to produce sound in less than 20 generations. The evolutionary equivalent of an S.O.S. - a last ditch effort to avoid extinction.
Check out the "Research" page to learn more about what you can do to help us understand the evolutionary causes and consequences of parasitism in this one-of-a-kind system, and how urbanization may threaten the livelihood of these crickets.
