Quick stats update

February 11, 2019

Trichoptera Ireland is now six years old. The website includes 75 published references related to caddisflies in Ireland gathered in one location (and more to come). I am delighted that the visitor numbers have continued to grow year-on-year. In 2018, the site had 2,989 visitors from 73 countries (up from 2,085 visitors from 73 countries in 2017). The Top 5 countries for 2018 were: United States, United Kingdom, Ireland, Germany and Norway.

There is now a species profile for each of the 153 Irish Trichoptera species available through the website.

Thanks to all my visitors. I hope you have found something useful here.

Hydropsyche fulvipes (Curtis, 1834)

Hydropsyche fulvipes is one of eight members of the Family Hydropsychidae found in Ireland, and one of six of the genus Hydropsyche. It is a species whose larvae can be found in small, generally first order, streams. Its substratum preference ranges from coarse gravel to boulders and bedrock, but includes plant material and woody debris, in areas with moderate to high current velocities. Its preference is for neutral to alkaline waters.

Hydropsyche fulvipes has a univoltine reproductive cycle (one generation per year) in temperate areas. Its feeding ecology is mainly passive filter feeding, with some predation and grazing.

Characteristic features of the larva of Hydropsyche fulvipes include the presence of large, rectangular dorsal plates on all three thoracic segments, tufted gills on the abdominal segments up to and including the 7th segment, the lack of long bristles on the front margin of the pronotum, partially pigmented posterior prosternites, a frontoclypeal pattern of joined aboral and lateral marks and a pale band on the anterior part of the ventral surface of the head (though this is not very dramatic). Its separation from other Hydropsyche larvae is difficult.

Adults of Hydropsyche fulvipes can be found on the wing from May to September.

Hydropsyche fulvipes was added to the Irish list after an adult female was captured in Edenvale, Co. Wexford on 14th August 2018 (O’Connor et al., 2019). Distribution records of Hydropsyche fulvipes in Ireland should soon be available here.

After a number of false starts, Hydropsyche fulvipes (Curtis, 1834) has been added to the Irish Trichoptera list by O’Connor et al., (2019). A female adult was taken on a tributary of the River Sow at Edenvale, County Wexford on 14th August 2018. This brings the list of Trichoptera known from Ireland to 153.
