We have an infestation here in Scots Bay on a lilac by our side door. It =

  Subject: [NatureNS] Lilac Leafminer


  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:

  Ana a photo of leaf damage done by the caterpillars at:

  Many thanks!
