BURKE: BUPRESTIS BIOLOGY

Pacific regions wherever its primary hosts, the true firs, occur; on 
August 11, 1915, Mr. F. B. Herbert found a male laeviventris mating 
with a female rusticorum but in the rearing of many specimens we have 
always obtained laeviventris from the pines and rusticorum from the 
true firs and douglas spruce except in the one indefinite instance men¬ 
tioned under laeviventris. 
Buprestis langii Mann.—South Dakota, Colorado, Montana, Utah, 
Washington, Oregon and California; flies from June to September; 
numerous specimens have been taken on alder and willow leaves and 
some specimens on the bark of pine trees and spruce trees but none 
have been reared from the wood. 
Buprestis striata Fab.—Thomasville, Georgia; one specimen taken 
on March 20, 1905, by Mr. W. F. Fiske on bark of longleaf pine (Pinus 
palustris). 
Buprestis aurulenta Linn, (lauta Lee.).—Montana, Colorado, Idaho, 
Arizona, Washington, Oregon and California; mines wood of injured, 
dying and dead trees; western white pine (Pinus monticola), sugar 
pine (P. lambertiana), yellow pine (P. ponderosa) and (P. ponderosa 
scopulorum), Jeffrey pine (P. jeffreyi), lodgepole pine (P. murrayana), 
digger pine (P. sabiniana), monterey pine (P. radiata), blue spruce 
(Picea parryana), sitka spruce (P. sitchensis) and douglas spruce 
(Pseudotsuga taxifolia); pupates and transforms to beetle during the 
summer and early fall; winters over as a beetle in the pupal cell in 
wood; emerges following spring and summer; flies from April to 
September; causes considerable damage to the wood of lightning 
struck, fire scorched, blazed and otherwise injured trees by mining the 
pitchy scars; may live for years as a larva in the wood; seems to occur 
throughout the range of its primary host, the douglas spruce. 
Buprestis villosa Lee.—California; appears to have been named from 
a woolly specimen of aurulenta. Such specimens occur quite fre¬ 
quently among typical aurulenta. 
Buprestis adjecta Lee.—Washington, Oregon, California; mines wood 
of yellow pine (Pinus ponderosa); flies from July to September; adults 
common in the Lake Tahoe region of California but the work appears to 
be scarce. 
Buprestis apricans Hbst.—Virginia, North Carolina, South Carolina, 
Georgia, Florida and Texas; mines wood of injured, dying and dead 
trees; loblolly pine (Pinus taeda) and longleaf pine (P. palustris); 
pupates and transforms to the beetle in the summer and fall; winters 
over as a beetle in the pupal cell in the wood and emerges in the early 
spring; lives for several years as a larva in the wood; flies from Febru¬ 
ary to May and probably all summer; causes considerable damage to 
the wood of blazed, fire scorched and otherwise injured trees especially
