Two-striped Grasshopper (Melanoplus bivittatus) Aptly named, they have a pair of pale yellow stripes running along the top of the body from above the eyes to the hind tip of the wings. Their eggs survive the winter, with the nymphs hatching by late April to early May. They are polyphagous — meaning they are capable of eating a wide variety of food and will cannibalize their own kind in times of food shortage.
