    Hendrik Van der Wal commented on "Discover Life: Point Map of Entomophaga grylli":

    According to the book "Ecology" econd edition by Manuel C. Molles Jr. on p.96 The fungi Entomophaga grylli also affects the the clear-winged grasshopper (Camnula pellucida). This grasshopper lives in the white mountains of eastern Arizona. This research was done by R.I. Carruthers and his colleagues (1992). Also I see an article which concludes that the fungi is found in Great-Britain and Ireland. (copied from 'details') "In Great Britain and/or Ireland: Animal / pathogen colony of Entomophaga grylli infects live adult of Orthoptera" Because of this information I think this map should be updated. Conclusion in my opinion this fungi is also found in Great-Britain, Ireland and Eastern-Arizona.
