Tinodes waeneri (Linnaeus, 1758)

Tinodes waeneri is one of nine members of the Family Psychomyiidae found in Ireland, and one of five members of the genus Tinodes. It is a species whose larvae can be found in lakes, rivers, streams and canals, on a substratum of gravel to bedrock, building galleries on rock surfaces in standing to slow-flowing water. The species shows no preference in relation to pH of the water and can be found in brackish water.

In temperate areas, Tinodes waeneri has a variable reproductive cycle and lives for up to one year. In terms of feeding ecology, the larvae are predominantly grazers, with some gathering, passive filter feeding and predation.

Defining features of the larvae of Tinodes waeneri include a lack of abdominal gills, labrum comprising a sclerotized plate, lateral plates on the 2nd and 3rd thoracic segments small, anal prolegs with almost no basal membranous section, pronotum lacking a black thickening towards the posterior-lateral corner, anterior section of 1st leg coxopleurite with two vertical black bars, pronotum with yellow ovoid markings, and frontoclypeus noticeably darker the adjacent areas of the head.

The adults of Tinodes waeneri can be found on the wing from April to November.

Tinodes unicolor (Pictet, 1834)

Tinodes unicolor is one of nine members of the Family Psychomyiidae found in Ireland, and one of five members of the genus Tinodes. It is a species whose larvae can be found in streams, on a substratum of gravel to bedrock, building galleries on rock surfaces in moderate to fast-flowing waters. The species shows a preference for alkaline water.

In terms of feeding ecology, the larvae are predominantly grazers, with some gathering and passive filter feeding.

Defining features of the larvae of Tinodes unicolor include a lack of abdominal gills, labrum comprising a sclerotized plate, lateral plates on the 2nd and 3rd thoracic segments small, anal prolegs with almost no basal membranous section, pronotum lacking a black thickening towards the posterior-lateral corner, anterior section of 1st leg coxopleurite with two vertical black bars, pronotum lacking ovoid yellow markings, and labrum uniformly pale.

Adults of Tinodes unicolor have only been found on the wing in July in Ireland, while in Britain the flight period is described as June to September.

Tinodes maclachlani Kimmins, 1966

Tinodes maclachlani is one of nine members of the Family Psychomyiidae found in Ireland, and one of five members of the genus Tinodes. It is a species whose larvae can be found streams and on trickling rock faces, including those on coastal cliffs, building galleries on the rock surfaces. The species shows no preference in terms of the pH of the water.

In temperate areas, Tinodes maclachlani has a univoltine (one generation per year) reproductive cycle, and lives for up to one year. In terms of feeding ecology, the larvae are predominantly grazers.

Defining features of the larvae of Tinodes maclachlani include a lack of abdominal gills, labrum comprising a sclerotized plate, lateral plates on the 2nd and 3rd thoracic segments small, anal prolegs with almost no basal membranous section, pronotum lacking a black thickening towards the posterior-lateral corner, anterior section of 1st leg coxopleurite with two vertical black bars, pronotum lacking ovoid yellow markings, labrum darkest at the posterior-lateral extensions, frontoclypeus with three similarly size pale spots, ventral surface of the 2nd thoracic segment with pigmented patch, and proleg dorsal surfaces with a single, distinct pale spot.

Adults of Tinodes maclachlani can be found on the wing from May to August.
