Habitat and Feeding Behavior 
The distribution of Cyphoderris corresponds roughly with the 
Cordilleran forest province (Gleason & Cronquist, 1964). In south- 
ern British Columbia C. buckelli occurs in the Dry Forest biotic 
area (Cowan & Guiguet, 1965) characterized by yellow pine ( Pinus 
ponderosa) and at higher elevations, by interior Douglas fir ( Pseu - 
dotsuga menziesii). Amelanchier (serviceberry), Balsamorhiza (ar- 
row-leaf balsam-root) and Berberis (tall Oregon grape) are common 
understory plants in this association. In spring the nymphs and 
adult females of C. buckelli feed upon the flowers of these plants; 
night collecting at blooms is a good way to obtain specimens. 
C. buckelli is also found in the Columbia Forest biotic area, the 
so-called interior wet belt of British Columbia. In 1977 we located 
large populations adjacent to Kootenay Lake near Boswell and at 
Rosebery on Slocan Lake. 
C. monstrosa does occur in Dry Forest e.g. at Monck Prov. Park 
in southern British Columbia, but it is typically encountered in Sub- 
alpine Forest. Lodgepole pine {Pinus contorta) and Englemann 
spruce ( Picea engelmannii ) are characteristic of the Sub-alpine 
biotic area. In the Kananaskis Valley of southern Alberta we 
observed nymphs and adults to feed upon staininate cones of 
lodgepole pine (this before the cones reach a ‘loose pollen’ stage). 
Consumption was established by identifying cone bracts in the feces 
of field-caught specimens. Also caged insects were given cones and 
in most cases overnight they ate large portions.
