Migratory Grasshopper, Melanoplus sanguinipes (Fabricius) (Orthoptera: Acrididae)
This native grasshopper is extremely adaptable, and found throughout most of North America. It is found in every state in the continental United States, and in every province in Canada. It is absent from only the northernmost, coldest regions of Canada, and from southern Florida and Texas. Its distribution does not extend south into Mexico.
In most areas of its range, migratory grasshopper produces a single generation, and overwinters in the egg stage. However, in southern portions of its range two generations may occur annually. Eggs hatch relatively early, usually beginning in early June but about a week after twostriped grasshopper, Melanoplus bivittatus (Say) begins to hatch. Hatching is protracted and may require up to six weeks in an area, resulting in asynchronous development of the population. Early hatching individuals mature early in the summer and have adequate time for reproduction whereas late-hatching individuals are handicapped by the onset of cold weather.
