[1] Species within the genus Stenodema are elongate with a longitudinal furrow between the eyes and are best distinguished by the coarsely and densely pitted prothorax.

This distinguishes it from other closely related species, notably S. calcarata which has two femoral spurs.

Adults which have overwintered and mated in the spring are green with an orange-brown hourglass marking down their back, and those born later in the year are beige or tan.

[2] This species has been found across transcontinental North America Eurasia and is commonly observed in grassy fields and wetlands.

[5] The specific name trispinosa means "three-spined" and refers to the three small spines on its femurs.
