Popular Leaffolding Sawfly – Phyllocolpa bozemani – Nematus tibialis

Poplar Leaffolding Sawfly (Nematus tibialis) Common Name: Poplar Leaffolding Sawfly Latin Name: Nematus tibialis Appearance:  The adult Poplar Leaffolding Sawfly has translucent wings and a black body, giving it a wasp-like appearance. The caterpillar-like larvae can have a variety of colors but most frequently have a greenish look. Host plants: The Poplar Leaffolding Sawfly gets its name from its primary food source, which is different varieties of poplar trees. In order to provide cover as they feed, the larvae are known for folding and binding leaves together to form shelters. Territory:  Folding Poplar Leaves Sawflies can be found wherever there are host plants, which are all over North America, Europe, and Asia. Damages caused by Poplar Leaffolding: Poplar Leaffolding Sawfly larvae can cause damage to poplar trees by nibbling on their leaves. The folded leaves provide a haven for the larvae, and extensive infestations can result in defoliation, potentially affecting the tree’s health. Life History and Habits:

• Eggs:In the spring, adult female sawflies lay eggs on poplar leaves.
• Larvae:When the larvae hatch, they feed on the poplar leaves and build shelters by folding and securing the leaves with silk.
• Pupa:Larvae pupate on the ground or in leaf shelters.
• Adult Sawflies:Adult sawflies emerge after pupation, and the cycle continues. Adults do not cause harm because they are primarily concerned with mating and egg-laying.
