Larvae of these small (0.2 to 0.3 inch, 5 to 8 mm long) beetles overwinter in the soil. Adult weevils emerge in late May and early June and feed on buds and expanding foliage of a variety of plants, especially sugar maple. The end result is truncated, frequently tattered, off-color foliage that is especially evident on sapling and seedlings. Phyllobius oblongus, one of the two most common species, is shiny, dark brown (Fig. 72), and disappears by midsummer. The other, Sciaphilus asperatus, is gray and feeds throughout the summer.
