Crambus uliginosellus (Zeller, 1850)

Wingspan: 18-23mm

A univoltine species on the wing from June to mid-August. An uncommon moth at Las Descargues and one that is more often encountered in the wet habitats of the Bave Valley and the wetlands of Lac Tolerme.

Heckford (1999, 2001 & 2003) describes the larvae feeding in silken tubes amongst Sphagnum capillifolium (but not other Sphagnum spp.) and Campylium stellatum var. stellatum, and fed on unidentified grass and Carex panicea growing through the Sphagnum; larvae were also found in silken tubes at the base of Eriophorum angustifolium growing through a Sphagnum sp. and in captivity they ate the Eriophorum.
