Wormaldia subnigra McLachlan, 1865

Wormaldia subnigra is one of five members of the Family Philopotamidae found in Ireland, and one of three Irish representatives of the genus along with Wormaldia mediana and Wormaldia occipitalis. This species can be found in large streams and rivers. The substratum preference ranges from coarse gravel to boulders and bedrock. Wormaldia subnigra has a preference for neutral to alkaline waters (pH ≥ 7) and is a filter-feeder, building long, tubular nets attached to rocks; feeding on organic particulate matter. The species lives for over one year.

The larvae of the Family Philopotomidae can be readily separated from those of other families by the fact that they possess a white membranous labrum, with a brush-like anterior margin, as opposed to a sclerotized labrum. The larvae of Wormaldia spp. are separated from the other genre in the family by the smooth curve of the anterior margin of the frontoclypeus. Separation from Wormaldia mediana, and Wormaldia occipitalis in particular, is difficult and adults are likely to be needed to identify to species.

Adults of Wormaldia subnigra can be found on the wing from July to October.

There are currently no records for Wormaldia subnigra available through the National Biodiversity Data Centre mapping system.

Wormaldia occipitalis (Pictet, 1834)

Wormaldia occipitalis is one of five members of the Family Philopotamidae found in Ireland, and one of three Irish representatives of the genus along with Wormaldia mediana and Wormaldia subnigra. This species can be found in small streams and trickles. The substratum preference ranges from coarse gravel to boulders and bedrock. Wormaldia occipitalis has a preference for neutral to alkaline waters (pH ≥ 7) and is a filter-feeder, building long, tubular nets attached to rocks; feeding on organic particulate matter. The species lives for over one year.

Separation from Wormaldia mediana, and Wormaldia subnigra in particular, is difficult and adults are likely to be needed to identify to species.

Adults of Wormaldia occipitalis can be found on the wing from March to October.

Wormaldia mediana McLachlan, 1878

Wormaldia mediana is one of five members of the Family Philopotamidae found in Ireland, and one of three Irish representatives of the genus along with Wormaldia occipitalis and Wormaldia subnigra. This species can be found in fast-flowing streams. The substratum preference ranges from coarse gravel to boulders and bedrock. Wormaldia mediana has a preference for neutral to alkaline waters (pH ≥ 7) and is a filter-feeder, building long, tubular nets attached to rocks; feeding on organic particulate matter. The species lives for over one year.

Separation from Wormaldia occipitalis, and Wormaldia subnigra in particular, is difficult and adults are likely to be needed to identify to species.

Adults of Wormaldia mediana can be found on the wing from July to August.

There are currently no distribution records for Wormaldia mediana on the National Biodiversity Data Centre mapping system.

Chimarra marginata (Linnaeus, 1767)

Chimarra marginata is one of five members of the Family Philopotamidae found in Ireland, and the only member of the genus Chimarra. It is a species whose larvae can be found in larger streams and rivers than the other species in the family, with a substratum preference ranging from coarse gravel to boulders and bedrock.

This species feeds via passive filter feeding, spinning net to catch particulate organic matter.

Notable features of the larvae of Chimarra marginata include presence of a white, membranous structure with a brush-like anterior margin rather than a sclerotized, plate-like labrum that is typical of caddisfly larvae. The species is separated other species in the family by the presence of a deep U-shaped notch in the fronto-clypeus (anterior margin of the head capsule).

Adults of Chimarra marginata can be found on the wing from June to October.

Records for Chimarra marginata on the National Biodiversity Data Centre mapping system can be found here.

Philopotamus montanus is one of five members of the Family Philopotamidae found in Ireland, and the sole Irish representative of the genus. This species can be found in upland, stony streams, often with rapids running over boulders. The substratum preference ranges from coarse gravel to boulders, with high current velocities. Philopotamus montanus has a preference for neutral to alkaline waters (pH ≥ 7) and is a filter-feeder, building long, tubular nets attached to rocks; feeding on small, particulate matter. The species exhibits a univoltine reproductive pattern.

The larvae of the Family Philopotomidae can be readily separated from those of other families by the fact that they possess a white membranous labrum, with a brush-like anterior margin, as opposed to a sclerotized labrum. Philopotamus montanus is identified by the presence of a shallow, v-shaped notch in the anterior margin of the frontoclypeus. In addition to this, the black pigment band running along the side of the pronotum is contiguous with the black band running across the rear of the pronotum.

Adults of Philopotamus montanus can be found on the wing from February to October.

Philopotamus montanus is also known by its common name yellow spotted sedge.

Records of Philopotamus montanus on the National Biodiversity Data Centre mapping system can be found here.
