The lodgepole sawfly (WMeodiprion burkei Midd.) (fig. 45), in 
the adult stage, is about one-third of an inch long. The males are 
black and the females brownish. The hairless, wrinkled bodies of 
the larvae are greenish or grayish, with lighter lateral and dorsal 
stripes, brown heads, and black eyes, and are about 1 inch long when 
mature. ‘This species developed a severe outbreak in 1921 over a 
large area of lodgepole pine at West Yellowstone, Mont. In the 
next few years a tremendous acreage of lodgepole pine was defoliated 
and a large percentage of the trees died. This outbreak was further 
complicated by a contemporary outbreak of the lodgepole pine needle 
tier (see p. 82). Control of both species along highways was effected 
by spraying with lead arsenate.
