Confidence: It's likely to be this, but I can't be certain.
Notes: I can't be sure the pronotum is punctured (which it should be in Stenodema, but not in Notostira). However I'm almost certain I can see the spurs on the inner side of the hind femur on the insect's right. If so this would have to be either S. calcarata (a very common species) or S. trispinosa. The latter is a very local species in my experience. However, the site you mention could just be to its liking - my 7 records all come from wetish land on the coast.
