Abstract. The bark beetles Ips pini, I. perroti and I. grandicollis are sympatric in pine forests of the north central
United States. They share the same limited phloem resource and often coexist within the same host trees. We
tested whether phloem resources are partitioned in time and space by measuring spatial and seasonal colonization of
logs. Differences among species in flight phenology, development time, voltinism and spatial colonization patterns
