Ozaena lemoulti

Distribution

Biology
Ant host: Camponotus ocreatus Over many years of collecting in Walker Canyon, one of us (WM) has noticed that ozaenines are only found associated with the largest Emory oak trees. Those old, but living, trees contain large dead portions, especially dead branches. Many of these trees are somewhat hollow in the middle of the trunk, and they have scars with holes on the bark left by fallenbranches that appear to lead into the hollow center of the trees. The large formicine ant, Camponotus ocreatus Emery, also frequents Emory oaks, and they are always found on the same large trees with ozaenines. We noted this pattern before [25],but explore it further here as Camponotus ocreatus is the most likely host ant of O.lemoulti larvae
