Puss moth

Harmful Effects of Puss moth

Cerura vinula

A species of Cerura

Puss moth larvae can cause severe defoliation of willow and poplar trees, leading to stunted growth and increased susceptibility to secondary infections. Infestations primarily affect plant health and may impact timber production and recreational spaces.

Damage Level
Mild to Severe
When puss moth larvae are numerous, severe defoliation of host trees such as willow and poplar can occur, leading to compromised tree growth. In contrast, a small number of larvae may only cause mild, often negligible damage. Large-scale infestations could affect recreational areas and timber production due to defoliation.

Damage Level
Mild to Severe
When puss moth larvae feed on the leaves of poplar and willow species, they chew plant tissues, leading to defoliation. This feeding habit can strip the foliage extensively, resulting in decreased photosynthesis, which undermines the plants' growth and vigor. The damaged areas also make the trees more susceptible to secondary infections or infestations.
