Meet Paroxya clavuliger, the olive green swamp grasshopper. This unassuming little spur-throated grasshopper is about 3-4 cm long (females are larger), and is also known as the salt marsh grasshopper and hoosier grasshopper.
Both sexes are primarily green to greenish-black, with black eyes, and a dark stripe through each eye, also running down the pronotum. The tibiae are blue-green, and the antennae are about the same length as, or longer than, the tibiae. In Florida, adults are found April-December, generally in wet areas with lots of grasses, such as the edges of ponds and marshes.
