Considerably dry and warm year 1999 and early droughts in spring and at the beginning of its summer moved whole ontogenetical cycle of the tree tergestinus (CHARPENTIER, 1825) and other interesting cricket about 2 weeks or more earlier than in 1998. For example there is a top of Epacromius in the floodplains of braided rivers of the Alps population density at the end of August in 1998 and at the beginning of this Orthoptera month in 1999 as well as in 2000.

Site 6 (fig. 12) Switzerland: Rh6ne river. The species was present in Visp (FRUHSToRFER, 1921), Siders/Sierre (many obs.) and Martigny (coll. Guy, Geneva Museum). The mention of Sion in THoRENS & Nnorc (1997) is an error due to a transcription failure (it was Siders = Sierre l). Prof. Dr. J0rg Zettel made the last observation of E tergestinus by the RhOne river in the Finges/Pfyn floodplain in 1989 (ZErrEL, 1997). Since then, 4 years of systematic searching in the area gave no result (cARRoN,1999). Other present interesting species . Chorthippus pullus, Sphingonotus caerulans, Tetix tuerki (in the Pfyn region).

Site 7 Switzerland: Rhein river. NADtc (1991) summarizes the formerly occupied sites along the Rhein in this region.

Site 8 Switzerland and Austria: Inn river. Several former populations in the swiss (Strada) and Austrian (Ried, Tosens) parts of the river (NADrc, 1991). Nnorc (1986) could see the last specimens in the 60ys, now the species is extinct. We visited all potential sites between Ardez (CH) and Landeck (A), without success. We did not check the Inn river between Landeck and lnnsbruck, the rrver rs Fig. 10: Giffre river, site with E. tergestinus.

Even though we Sailx spp. on the isies and riverbanks. discovered very good habitats by the austrian Lech river, in the Forchach region, Epacromius could not be found. Other present interesting species : Chorthippus pullus was observed by the members of the Swiss Orthoptera group in 2000, in the Scuol area (CH). We could see Bryodema tuberculata and Chorthippus pullus in Forchach (A).

Site 9 (Fis. 13) Switzerland and ltaly: Rom (Adigo affluent) and Adigo rivers. Former occupied sites in the Swiss M0stair Valley and in the ltalian Venosta Valley (Nnorc, 1991). Now extinct in all Swiss and most ltalian sites, only one population left, discovered by Stefan Pliiss in 1988 (Nnotc, 1991) in Prato al Stelvio by the Rom river (Lg 10.33 Lat 46.4), altitude .920 m a.s.l. We could not find the species in the site in 1999. Thomas Wilhalm (Natural History Museum of Bolzano, pers. com.) told us that only a couple of larvae had been found in 2000. The population of E tergestinus can be considered as almost extinct in this site (and thus in the Italian Alps). Other present interesting species : Thomas Wilhalm (pers. com.) reports letnx tuerki, that we did not see.
