pairs of
feet. The color is yellowish-white, the front of the head being
blackish. Probably, about midsummer, with a possible variation
of two mouths in each direction from this date, the parent
beetle deposits her eggs, preferably on a small twig of the
preceding year's growth. Upon hatching, the young larva
commences to eat the tender wood just beneath the bark, and
later enters the center of the twig and works toward its base.
In this manner it works its way into the main limb, which may
be of considerable size, and feeds within it for a period of
about three years. The burrow thus becomes several inches in
length, in many cases. Just before transforming to pupae some,
but not all, of the larvae, cut the wood for the purpose of
dropping the branches, as before described. Limbs in which the
immature larvae are working often break off with ragged end when
bent with the hand.

should be given nearby oak and hickory limbs, which have

THE PECAN TREE BORER (_Sesia scitula_): The moth of this insect is
clear-winged and closely resembles the moth of the peach tree borer.
Little is known of its life-history.

"It[N] is probable that the eggs are deposited by the female moth on the
bark of a tree near a fresh wound. For example, near newly set buds. The
eggs hatch and the larvae bore into the bark, and there live for a time,
eating out the soft inner-bark and tender wood. It is certain that the
borers live in these situations the over winter and change to pupae in
the spring, from which the moths emerge in April. The moths I reared
appeared April 3rd, 4th and 6th. The pupae are in cocoons, just under the
bark. The cocoons are made from excrement and bits of bark that have
been fastened together with silk similar to the cocoons of the peach
tree borer. Whether these moths, that emerge in the spring, lay eggs and
produce a brood in the summer, that in turn develops a fall brood of
larvae, I am unable to say."

"The[O] young borer is apt to gain entrance to the sapwood through some
wound in the bark, such as a graft-union, and here it feeds, sometimes
completely girdling the sapwood above and below the wound. It is said to
prefer to attack buds that have been budded on old, large trees. As a
general rule the burrows ascend the tree in a spiral about the trunk, so
