FIGURE 45.—Adult of Chari- 
essa pilosa, a predator of 
wood-boring larvae. 
E’noclerus nigripes (Say) larvae feed on bark beetles in coni- 
fers, and on wood borers in hardwoods. Adults are brightly col- 
ored and about 8 to 12 mm. long. The head, thorax, base of the wing. 
covers, and the undersides are dull red; the remainder is black 
except for two yellowish cross bars on the wing covers. The 
larvae are similar to those of Thanasimus dubius. The black- 
bellied clerid EH. lecontet Wolc., has many hosts including bark 
beetles and weevils in pine, spruce, and juniper. It also feeds on 
bark beetles, weevils, and small borers in hardwoods. 
Monophylla terminata (Say) feeds on borers and bark beetles in 
hardwoods. There also are reports of its feeding on white pine 
weevil larvae in white pine. Adults are about 4 to 8.5 mm. long. 
The eyes are deeply notched in front, the last joint of the antenna 
is as large or larger than all of the others combined, the thorax is 
yellow with a black disk, and the sides of the wing covers are 
yellow. The larvae are white, soft-textured, and bear two well- 
separated hooks on the ninth abdominal segment. 
Cymatodera bicolor (Say) is an important enemy of round- 
headed and flat-headed borers in hardwoods in Eastern United 
States. Adults are about 5 to 10 mm. long. The color is dull 
blackish except for the legs, thorax, and basal joints of the an- 
tennae which are reddish-yellow mixed with black. The larvae 
are purplish. 
Tarsostenus univittatus (Rossi) is an important predator of 
powder-post beetles and other borers in dry, seasoned wood. The 
adult is small,slender, and shiny black except for a white mark 
across the middle of the elytra. The larva is very small and a
