Catocala nymphaea

Nymphaea moth

Description

Catocala nymphaea, known as the nymphaea moth, belongs to the family Erebidae. It is primarily distributed in the Mediterranean region, inhabiting evergreen forests and maquis dominated by Quercus species. Its range includes southern France, Greece, Italy, North Africa, and extends to Anatolia and parts of Central Asia. Rare sightings have been recorded further north in Europe.

The larvae feed on Quercus ilex and Q. coccifera, causing defoliation of these evergreen oaks. Larval feeding can reduce the photosynthetic capacity of the host tree, particularly when infestations are intense. Eggs overwinter on the host tree, with larvae emerging in spring and feeding through early summer. Adults, which have a wingspan of 54–62 mm, are active from July to September.

Symptom

Infested trees exhibit chewed leaves, particularly on evergreen oaks like Quercus ilex. Leaf edges are irregularly damaged, and severe infestations may lead to partial defoliation.
