Ecological notes .

The association of this species with the host-plant Cyrtandra cordifolia was previously reported by Gagné (1968). Further specimens have been subsequently collected on C. propinqua C. N. Forbes and C. waianaeensis H. St. John & Storey. Engytatus confusus therefore seems to occur on at least three species of Cyrtandra on Oahu, one of which is also utilized by E. terminalis . This once again indicates that individual host-plant association is not a strong isolating mechanism for the Oahu Engytatus species feeding on Cyrtandra .
