Lymantria dispar dispar (LDD)

Help Protect Markham’s urban forest

Lymantria dispar dispar (LDD) is a non-native invasive, defoliating insect that prefers to feed on oak tree leaves, but will feed on the leaves of many other hardwoods including maple, elm, birch, poplar and willow trees.

The caterpillars tend to only feed and damage trees for a short period in June and July. Learn more about LDD on the York Region website.
