Maybe this species has a wider range than is commonly recorded, and maybe it's not as rare as its Red Data listing as vulnerable would suggest. Michael corrected my M.alpina ID of the photos I took in Slovenia (where I found masses) to M.irena http://www.ispot.org.uk/node/239488#comment-66640 and Slovenia is within the range recorded on Fauna europaea, but this record near Milan would be well to the west of the range they show.

Miramella alpina ist in den Pyrenäen, in den Nordalpen, im Schwarzwald, in den Vogesen, im Schweizer Jura und Bayerischem Wald sowie in den Karpaten verbreitet. In den Südalpen, etwa im Tessin, kommen weitere ähnliche Arten (Miramella formosanta) vor.
The recorded range http://www.eu-nomen.eu/portal/taxon.php?GUID=urn:lsid:faunaeur.org:taxna... and appearance http://www.linnea.it/orthoptera-cavallette-grilli/miramella-formosanta.php do seem to fit for M. formosanta - so that seems most likely without inspecting further.
