Neureclipsis bimaculata (Linnaeus, 1758)

Neureclipsis bimaculata is one of eleven members of the Family Polycentropodidae found in Ireland, and the only member of its genus. It is a species whose larvae can be found in rivers, streams and lake outflows. Its substratum preference includes plants and mosses, woody debris, gravel, rocks, boulders and bedrock. This species shows a preference acidic water, and can be found in brackish water areas.

The feeding ecology of Neureclipsis bimaculata is predominantly predation, with a small amount of passive filter feeding, using trumpet-shaped nets, with a narrow posteriors section, which curls forward.

Characteristic features of the larva of Neureclipsis bimaculata include a basal membranous section of the anal proleg equal in length to the distal sclerotized section and pair of strong spines on the ventral surface of the 9th abdominal segment.

Adults of Neureclipsis bimaculata can be found on the wing from May to October.

Holocentropus picicornis (Stephens, 1836)

Holocentropus picicornis is one of eleven members of the Family Polycentropodidae found in Ireland, and one of two of the genus Holocentropus. It is a species whose larvae can be found in ponds, lakes, canals and other still waters. Its substratum preference is for plants and mosses and this species can be found in brackish water areas.

Holocentropus picicornis lives for up to one year and is univoltine (one generation per year) in temperate regions. Its feeding ecology is predominantly predation, with a small amount of passive filter feeding, using tubular nets attached to plants.

Characteristic features of the larva of Holocentropus picicornis include a basal membranous section of the anal proleg equal in length to the distal sclerotized section, the tarsus and tibia of the 1st leg of about equal length, right-angled anal claws and dark bands on the dorsal surface of the head capsule (a feature shared by Holocentropus stagnalis, which has not been confirmed for Ireland).

Adults of Holocentropus picicornis can be found on the wing from May to September.

It is a species whose larvae can be found in ponds, lakes and slow-moving rivers. Its substratum preference is mainly for plants and mosses, but also stones and gravel. It shows a preference acidic water, and can be found in brackish water areas.

Cyrnus trimaculatus lives for up to one year. Its feeding ecology is predominantly predation, with a small amount of passive filter feeding, using tubular nets attached to plants.

Characteristic features of the larva of Cyrnus trimaculatus include a basal membranous section of the anal proleg equal in length to the distal sclerotized section, the four blunt teeth on the inside of the anal claws, and the dark band on the dorsal surface of the head.

Adults of Cyrnus trimaculatus can be found on the wing from May to October.

Tricholeiochiton fagesii (Guinard, 1879)

Tricholeiochiton fagesii is one of 25 members of the Family Hydroptilidae found in Ireland, and the only member of the genus Tricholeiochiton. It is a species whose larvae can be found in weedy ponds, lakes and bog pools. Tricholeiochiton fagesii has a case made of silk secretions, which is laterally compressed and has anterior and posterior openings of similar size and shape. Only the final instar has a case, and is very different from the earlier instars.

The larvae of most Hydroptilid species are not described. Defining features of the final instar of the larvae of the genus Tricholeiochiton fagesii is the absence of dorsal and ventral ovoid processes on the abdomen, no lateral protuberances on the 2nd abdominal segment, no median sclerotized point on the labrum, 2nd and 3rd legs 4-5 times as long as 1st leg, and a case as described above.

Adults of Tricholeiochiton fagesii can be found on the wing in July.
