Comment on this leafhopper posted on Wisconsin Entomological Society FB page after someone else decided to investigate -- from Dr. Chris Dietrich, Entomologist Illinois Natural History Survey, he replied "Yes, this is B. rubrostriata. I'm not aware of any records from states north of Oklahoma. Species of Balclutha (a diverse genus with several species native to the USA as well as most other parts of the world) are highly mobile insects so it's not too surprising to find them this far north, especially this late in the season and how quickly they have spread following their introduction into the southern US. We often get Dalbulus maidis, the corn leafhopper, a related species that does not overwinter in Illinois but nonetheless migrates north from its breeding grounds in the Gulf Coast and Mexico over the course of the summer when weather conditions are favorable for dispersal. These individuals die off during the winter and then it takes most of the following summer for a few to make their way north again. I suspect the same is happening with B. rubrostriata. It will be interesting to see whether this becomes a persistent pattern."

Cool! I'll post it on the Wisconsin WES page and see what they say. Well, maybe not cool since I just found a page which describes this leafhopper as an invasive species.
