Orthoptera offer among the best systems with which to study the multitude of processes that cause speciation. What propelled the ancestral Orthopteroid into the many thousands of species we see in evidence today? This is a daunting question and an answer requires knowledge at many levels.
In this talk, I will ask a related but more tractable question: How do closely related species of Orthoptera differ? Detailing observations, along with speciation theory and evolutionary insights, we can systematically propose how new species arise in various groups, and then contrast and evaluate the mechanisms of speciation that have been famously debated in the Orthoptera.
