The Lilac borer moth larva (Podosesia syringae) is in Toronto, Ontario, Canada, on July 09, 2025. The Lilac borer larvae, also known as ash borer larvae, are the immature, destructive stage of the lilac borer moth. They tunnel into the wood of lilac, ash, and privet trees, feeding on the phloem and outer sapwood. This feeding activity weakens the tree, creating tunnels that can be up to 32 cm long. The tunnels can lead to dieback, branch breakage, and potentially the death of the tree, especially if the tree is already stressed.
