re: "Lister and Garcia attribute this crash to climate. In the same 40-year period as the arthropod crash, the average high temperature in the rain forest increased by 4 degrees Fahrenheit. The temperatures in the tropics stick to a narrow band. The invertebrates that live there, likewise, are adapted to these temperatures and fare poorly outside them; bugs cannot regulate their internal heat."
No doubt, this is alarming. None the less, couldn't this suggest that the species in question simply moved to more suitable climate? That is, there is a difference between being killed off, and leaving an area that no meets their needs.
