The findings reveal that insects developed modern patterns of herbivory long before flowering plants flourished, upending a long-held hypothesis Jack Tamisiea Paleontologist Conrad Labandeira ...

This research may help predict how climate change will impact insect distribution and behavior. Tiny cold-blooded animals like flies rely on their environment to regulate body temperature. Their ...
