Cerura delavoiei (Gaschet, 1876)

Host plants:
The caterpillars live on poplars and willows (Salicaceae). I found cocoons on Salix canariensis in La Gomera (Canary Islands).

Habitat:
Cerura delavoiei inhabits river valleys and other places with the host plants. In La Gomera it is found between 150 and 1200m above sea level along streams and willow sites in the laurel forest, e.g. on roadsides.

Life cycle:
Cerura delavoiei probably has several generations. The pupae overwinter respectively survive initially the summer and then the cooler season when the willows are partially bald. The cocoons are observed also several years after emergence still often on the willow trunks. The moths fly especially in spring and early summer, but in total between Christmas and in the summer.

Remarks:
Cerura delavoiei is similar Cerura vinula and is in North Africa and on some Canary Islands (about La Gomera, Gran Canaria, Spain) spread.
