As the name = suggest, the young larvae initially mine leaves leaving discoloured = green blotches on the leaves which eventually turn brown. As the larvae = mature the exit the leaves and collectively roll up the leaves to create = a tube in which they live and on which they feed. In lilacs here in = Halifax they can cause a significant amount of defoliation by the end of = the season. This is an European species which was inadvertently introduced to = North America, first appearing in Ontario in 1923. I'd be very = interested in ascertaining how widely distributed this species is in = Nova Scotia. The damage the cause is quite characteristic. If you've = noticed this damage on lilacs, I'd appreciate hearing where and when. = There is a good photograph of the moth located at: http://www.danske-natur.dk/images6/mor1030a.jpg Ana a photo of leaf damage done by the caterpillars at: http://www.gov.pe.ca/photos/original/af_lilac_LM.jpg Many thanks!
