Analysis of information sources in references of the Wikipedia article "Odontomachus" in English language version.
One species called Odontomachus haematodus was unofficially recorded in Alabama back in 1956. But now researchers have officially confirmed that the species has spread across the Gulf Coast, at least as far east as Pensacola, Florida.
As recently as a few years ago, another species called Odontomachus ruginodis was thought to be confined to the Orlando region, and points south. But now Sorger has confirmed a record of ruginodis more than a hundred miles north of Orlando, in Gainesville, Florida.
Not all of the trap-jaw species are on the move, however. Sorger also studies Odontomachus relictus, a species that is found only in endangered scrub habitat on central Florida's ancient sand ridges.
