Ecological notes .

This species has been previously recorded as occurring on several species of Railliardia ( Gagné 1968), a host-plant genus subsequently synonymized within Dubautia, in the Asteraceae . Based on these records and examination of other Bishop Museum specimens, E. hawaiiensis occurs on Dubautia menziesii (A. Gray) D. D. Keck, D. platyphylla (A. Gray) D. D. Keck, and D. thyrisiflora (Sherff) D. D. Keck, and thus is not strictly confined to a single host-plant species within this genus.
