Small Bombus ternarius workers for age most frequently on the distal parts of goldenrod flower clusters when large B. terricola workers are present. This shift results from B. ternarius avoiding B. terricola. In this way B. ternarius can exploit, without conflict, resources whose availability changes constantly because of fluctuating numbers of larger consumers.
