The eggs hatch the same summer; the larva hibernates under ground, continues eating and growing the next summer, and does not even then reach its full development, but winters a second time and pupates the following spring.
A sham fruit filled with sham seeds; each seed-like growth contains a grub, which later in the season pupates and eats its way out, a winged insect. How foreign to anything we know as mechanical or chemical it all is! the surprising and incalculable tricks of life!
On the young limbs and small trunks the bark is tight and close, not splitting into seams or furrows with the expansion of the cylinder but stretching and throwing off detached flakes and chips. Under the chips various insects hide or make some of their transformations. There the codlin-moth pupates. The old remains of scale insects may be found on the exterior.
Associated with this weevil we have found the smaller, rounder, more cylindrical, whitish grubs of the Hylurgus terebrans, which mines the inner layers of the bark, slightly grooving the sap-wood. Later in April it pupates, and its habits accord in general with those of Pissodes strobi.
