Excerpt from Studies of Life Histories of Leafhoppers of Maine Its presence in meadows is almost universal and while it is not so abundant here as some of the other species probably because of its migration to adjacent grain fields, it must be counted as a constant drain especially in meadows of several years standing. On account of its numerous broods rapid development of the nymphs and ready flight of the adults it is more rapidly distributed into new fields than most of our meadow species and consequently rotation may not be as effec tive in its control. As a pest of oats it is one of the most conspicuous in its at tack oi any of the oat-feeding species although its work is very easily mistaken for that of plantlice or thrips. In Maine the attack on oats begins almost as soon as the plants are above ground when their succulent character is evidently a distinct attraction to the leafhopper and at this time adults may be swept in numbers from oat fields especially if they are adja cent to old meadows. It is possible that there are two brood here before the ripening of the crop but we have complete evi dence of the development of one generation both by rearing on plants in cages and by field observation This generation begins with egg depositions in the oat leaves in early July as detailed under life history and matures by the middle of Au gust or before the ripening of the grain and is then ready for flight to fields of more succulent character than the oat stubble.
