Pygmy Grasshopper - Tetrix arenosa

The pygmy grasshoppers, Orthoptera family Tetrigidae, can be recognized by their long pronotum, which extends far back over the abdomen, ending in a point. These grasshoppers are all less than 20mm long. Most are brown, and a few species have long functional flying wings. Females are larger than males. Adults and nymphs feed on algae and other organic material in wet soil. Also called grouse locusts.

This view shows the dorsal and ventral valves of the ovipositor - one sure indication this is a female of the species. Also quite apparent is the long, tapered pronotum extending almost to the tip of the wings.
