Abstract

A species of Mompha, discovered on creeping water-primrose Ludwigia adscendens (Onagraceae) in Assam, N.E. India, is described as new and named Mompha ludwigiae. The eggs, larval and pupal stages are also described. Females lay up to 150 eggs in 3–7 days; development from egg to adult takes 3–5 weeks, the larva at first mining the leaves and later feeding externally on terminal shoots. The larvae could be reared on Oenothera rosea, L. perennis and L. octovalvis in the laboratory, but no host-plants other than L. adscendens were found in the field. A Eulophid parasite, Euryscotolinx sp., has been bred from pupal cocoons.
