Species profile: Ecclisopteryx dalecarlica

July 19, 2017

Ecclisopteryx dalecarlica Kolenati, 1848

Ecclisopteryx dalecarlica is one of 40 members of the Family Limnephilidae found in Ireland, and the sole member of the genus Ecclisopteryx. It is a species whose larvae can be found in rivers and larger streams. Its substratum preference is for stony material from gravel to cobbles and boulders, in moderate to fast flowing water. Ecclisopteryx dalecarlica has a curved case made of mineral grains. The species can be found in brackish waters.

The feeding ecology of the larvae of Ecclisopteryx dalecarlica is almost entirely grazing, with small amounts of shredding and gathering.

Characteristic features of the larva of Ecclisopteryx dalecarlica include a prosternal horn, dorsal protuberance on the 1st abdominal segment, antenna midway between the eye and the anterior head margin, gills with only single filament, two central anterior-median sclerites on the metadorsum, no teeth along the mandible edges, additional setae on femoral faces, lateral protuberance without a posterior sclerite and a group of pale setae between the eye and the frontoclypeal apotome.

Adults of Ecclisopteryx dalecarlica can be found on the wing from May to June.
