Deltote uncula (Clerck, 1759)

Host plants:
In contrast to Deltote bankiana the caterpillar of the species feeds mostly on sedges (Carex).

Habitat:
Deltote uncula inhabits fens and species-rich, extensively managed wet meadows with high proportion of Cyperaceae.

Life cycle:
The pupa hibernates. Depending on the altitude, the moth flies from May to August in one or two generations. In case of a single generation the main flight period is in June. The caterpillar lives from June to September.

Endangerment factors:
Deltote uncula has already lost many habitats by increasingly intensive agricultural use of wetlands (fertilization, dewatering, frequent mowing, transfer into arable land) on the one hand and reforestation and bush encroachment on the other.

Remarks:
The distribution extends from the Pyrenees through Central Europe and temperate Asia to Japan.
