This species, unlike the others, places its eggs in long rows, one above the other, and the punctures are so numerous that the stems frequently break at the points punctured. This is particularly true of the raspberry, and makes the cricket a pest of serious economic importance under some conditions. The female cricket may lay from one to a dozen or more eggs in a night and continue the process every night or with occasional intermissions until from twenty-five to seventy-five eggs are Fig. 31.— Snowy Tree Cricket. a, Egg punctures and cankers in apple wood, (X 1£); b, egg in raspberry (X 2\); c, egg in apple bark (X 15); d, egg cap (X 50); e, spicule of egg cap (X 500). The eggs are much longer than wide, are etched over most of the surface with cross-hatched scratches, and each has a cap covered with minute mound-like or teat-like projections. The size and shape of the cap differs with the different species and serves as a means of identification. The nymphs of the tree crickets begin to emerge from the eggs during early June, and the hatching process is a most interesting one. When the egg hatches, the cap at the outer end breaks off, leaving its trace on the head of the emerging nymph in the shape of.
