    Limber pine (Pinus flexilis James) ranges in latitude from 33°N to 51°N and in elevation from 870 m above sea level (asl) in North Dakota to ~3400 m asl in Colorado (Burns and Honkala 1990). In the central Rocky Mountains, limber pine co-occurs with many tree species due to its broad elevational range (Peet 1981). Limber pine seeds are large, generally wingless, and dispersed by birds (Lanner and Vander Wall 1980). While it is known that seeds of limber pine in Colorado are eaten by animals such as Clark’s Nutcrackers (Nucifraga columbiana Wilson), black bears (Ursus americanus; McCutchen 1996), and small rodents, little information is available on insect utilization of cones and seeds of limber pine for food and habitat.
