--Apple-Mail-75-1023876758 Content-Transfer-Encoding: 7bit Content-Type: text/plain; charset=US-ASCII; delsp=yes; format=flowed Hi folks, I've spent a fair bit of this weekend battling an infestation of Lilac Leafminer (Gracillaria syringella), the caterpillar of a small moth in Gracillaridae, which is attacking the lilacs in my backyard. 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!
