Species profile: Apatania muliebris

February 17, 2016

Apatania muliebris McLachlan, 1866

Apatania muliebris is one of three members of the Family Apataniidae, and of the genus Apatania, found in Ireland. It is a species whose larvae can be found in streams and trickles, on a substratum ranging from gravel to boulders and bedrock.

In temperate areas, Apatania muliebris is thought to have a univoltine reproductive pattern (one generation per year), though it is possibly bivoltine (two generations per year). In terms of feeding, this species is both a grazer/scraper and a gatherer/collector.

Characteristic features of the larva of Apatania muliebris include the presence of a prosternal horn visible on the ventral side of the pronotum (can be difficult to see without manipulating the legs), a dorsal protuberance on the 1st abdominal segment, lack of folds on the ventral apotome, single gill filaments on the abdomen, a lack of anterior-median sclerites, mandibles lacking teeth, and long, tapering setae on the anterior edge of the pronotum.

Adults of Apatania muliebris can be found on the wing from April to September.

Records of Apatania muliebris on the National Biodiversity Data Centre mapping system can be found here.
