This species rolls the leaves of oak. Bar Harbor beating June 16. Rare. A. RHois Boh. (16369). Occurs on hazelnut and alder. As described by Packard, the singTilar, thimble-like rolls of this weevil may be found in June and July on the alder. When about to lay her eggs, the female begins to eat a slit near the base of the leaf on each side of the midrib, and at right angles to it, so that the leaf may be folded together. Before beginning to roll up the leaf she gnaws the stem nearly off, so that after the roll is made, and has dried for perhaps a day, it is easily detached by the wind and falls to the ground. When folding the leaf, she tightly rolls it up, neatly tucking in the ends, until a compact cylindrical solid mass of vegetation is formed. Before the leaf is entirely rolled she deposits a single egg, rarely two, in the middle next to the midrib, where it lies loosely in a little cavity. These rolls remain on the bushes sometimes for several days, but probably drop by the time the larva escapes from the egg, and it seems probable that the grub uses the roll for a shelter until it matures and is ready to enter on its transformation to a beetle.
