Note: this blog is about the non-native, highly invasive moth species Lymantria dispar dispar, which we have previously referred to as the Gypsy Moth. In this article, we will refer to the moth using its scientific name and the acronym LDD.
If you’ve seen an Ontario oak tree recently, you’ve likely been introduced to the invasive LDD Moth (Lymantria dispar dispar).
LDD Moth caterpillars were first introduced to North America in the late 1860s, and are voracious eaters! Their favourite cuisine is oak leaves, but in particularly bad outbreak years — like this one — they can spread to many other tree species.
