Clostera curtula (Linnaeus, 1758)

Host plants:
The larvae feed on Salix and Populus species.

Habitat:
Clostera curtula can occur almost anywhere where the host plants grow, especially in flood plains, marshes and softwood rich clearings in the forest.

Life cycle:
In the lowlands, Clostera curtula usually flies in two generations as Clostera pigra. In the higher mountains, where Clostera curtula is getting scarce fast, only one generation is formed in the summer.

In Northern Greece (Lake Kerkini), I observed larvae in all instars on poplars already in mid-May 2011.

Endangerment factors:
Clostera curtula is relatively low threatened, most likely locally by destroying softwood sites (e.g. along rivers).

Remarks:
Clostera curtula is widespread in Europe and temperate Asia to eastern China.
