European pine shoot moth

Rhyacionia buoliana

This moth could harm our forestry industry. It nestles in growing pine shoots, deforming the tree's growth.

About the European pine shoot moth

This moth is a native of Europe. It has spread to other countries and is now a major pest in Chile.

The females can fly several kilometres. Large areas can soon become infested with offspring.

Global distribution of the moth

Why this is a problem for New Zealand

The caterpillars make holes and galleries (tunnels) in the growing shoots of pine trees. This damage can cause the tree to grow crookedly and can kill the growing shoot.

While they may not die, trees infested with this moth will be shorter and narrower than unaffected trees.

How could it get here?

The only likely way for the moth to get here is in part of a pine tree, such as a stem, branch, or shoot.

How to identify the European pine shoot moth
