Major taxonomic revision! After decades of work, Dave Weissman and Dave Gray have finally published a monograph on Gryllus of the USA and Canada. We name 17 new species and discusses several additional taxa potentially deserving species status. In a separate paper, we present a molecular phylogeny of the group based on just shy of 500,000 base pairs of DNA from 563 loci.

In three allopatric sister species of field crickets, we found that female driven pre-zygotic isolation is stronger than male driven pre-zygotic isolation, and that total pre-zygotic isolation exceeds post-zygotic isolation.
