Unidentified Grasshopper

I've been researching for a reference for my suggestion, but I can't seem to find a good enough one, yet here's a link: http://www.inaturalist.org/taxa/seaside_... -> I'm not an expert, but since you said you found it in a coastal area, it seems to me that's the one. I've seen a few myself in my area (Portugal) and they look alike yours. All I can find is pictures in the internet, and I'm unsure that proves anything: (Ex: http://www.pbase.com/red_slough_wma/imag... )
