Distribution Portugal. Azores: Terceira ( Lopes et al. 2010). Madeira: Madeira Island ( Aguiar 2009); Porto Santo ( Aguiar et al. 2019). Mainland: Aveiro (iNaturalist, Appendix 1); Faro (this study; iNaturalist, Appendix 1); Leiria, Portalegre (iNaturalist, Appendix 1).

Host plants Portugal. Oleaceae : Olea europaea subsp. europaea L., Phillyrea angustifolia L. (this study); O. europaea L., O. maderensis (Lowe) Rivas Mart. & del Arco ( Aguiar 2009); adults were collected on Picconia excelsa (Aiton) DC. , which is a potential host ( Aguiar et al. 2019).

Parasitoids. Hymenopteran parasitoids of three genera emerged from mummies in the laboratory: Psyllaephagus ( Encyrtidae ), Pachyneuron ( Pteromalidae ) and Apocharips ( Figitidae ). The encyrtid is probably Psyllaephagus euphyllurae (Masi) , the most important parasitoid of E. olivina in the western Mediterranean Basin ( Triapitsyn et al. 2014). Triapitsyn et al. (2014) considered Pachyneuron and Apocharips to be hyperparasitoids of P. euphyllurae .

Comments. Immature E. olivina secrete white waxy flocculence resembling cotton; the secretions are usually found on the inflorescences or in the axils of small branches. The secretions by E. olivina on Olea europaea subsp. europaea and Phillyrea angustifolia appear identical.
