The upper photograph is a common meadow katydid (Orchelimum vulgare) and its ovipositor can be seen curving upwards beyond the end on the abdomen. These katydids are found in the eastern United States, except for Florida and the adjacent coastal plain. The adults are present from about July until late fall in marshes and in grassy areas such as meadows and roadsides.

The middle photograph is of a different species of meadow katydid, possibly O. nigripes. The legs are darker below the femur and the face is pink. In another photograph it can be seen that the antenna is about 3 times the body length.

The female in the lower photograph is laying eggs inside a stem in which she has made a slit. One of the antennae in this female seems to have been broken.
