(1906, p. 578) has taken it from the leaves of scrub oak, 
and Smith (1909, p. 293) reports the “larva in grape and 
chestnut.” We find no previous record of its having been 
obtained from a coniferous species. 
The females of this small buprestid deposit their eggs in 
dying or recently killed larch — and other trees — choosing 
limbs of a diameter of from three-fourths of an inch to one 
and a half inches. The larval burrows, in common with 
those of most flatheads, are considerably broader than they 
are deep. They are constructed immediately under the bark, 
grooving both bark and sapwood, but nearly all of their 
depth is excavated from the sapwood. The course of their 
burrow is at first longitudinal and is not excessively tortuous. 
(Fig. 22.) The width of the burrow at the start is about — 
one millimeter and by the end of the first year this has 
about doubled. The burrow made by the larva during its 
second season is much more variable both in diameter and 
in direction. The final result may be a very tortuous burrow 
which repeatedly crosses and recrosses its own course, or it 
may consist of an irregular broad area, as shown in Fig. 22. 
The entire larval mine is tightly packed with frass, and that 
derived from the bark and from the sapwood is usually so 
arranged as to form alternate dark and light bands or striz 
just as in C. blanchardz. 
The larva completes its growth during the second summer 
and then constructs a shallow pupation chamber in the outer 
sapwood. This extends diagonally down into the wood for 
a distance of from 6 to9 mm. The larva apparently pupates 
with its head toward the larval burrow, egress from the 
pupal chamber being obtained through the larval entrance. 
Exit of the larva through the bark is made through a small 
oval (sometimes nearly semi-circular) opening, which can 
be readily distinguished from those of the other buprestids 
by its small diameter. 
Insects associated with Anthaxia quercata form the typical 
limb association and comprise Neoclytus longipes and the 
species previously listed as bred from the same source.
