The natural presence of this beetle on som plantations, Persea bombycina Kost. (Lauraceae) at Farm No. 3 Central Muga Eri Research and Training Institute, Lahdoigarh (Jorhat-Assam) has been documented with appreciable damage during May to August, 2010. The host range, distribution, biology and bionomics of E. fornicatus (Eichhoff) have been discussed in this manuscript along with the new record on P. bombycina Kost for the first time.
