Distribution: Albania, Bulgaria, Croatia, Czech Rep., Finland, France, Germany, Great Britain, Norway, Slovakia, Slovenia, Spain, Sweden, Switzerland; Russia: RUE, North Caucasus; Georgia. Note: see the manual for abbreviations: present-day Russia. Region(s): Westpalaearctic General note: According to Stary and Stubbs, 2015, probably more widely distributed in Europe. For Norway check Olsen et al., 2018, and citations below. For Great Britain check Stubbs, 2021, and citations below. There is a drawing of perhaps imbecilla in Tjeder and Andersson, 1989, probably from Sweden.

Olsen et al., 2018: 145 (For Great Britain the following habitats have been listed: calcareous seepages on rock faces or other rather bare surfaces or depositing tufaceous substrate, along spring- fed streams associated with seepage complexes, shaded woodland, large woodland stream well below the source, within ravine or in tall herbage close to a waterfall splash zone (Stary & Stubbs 2015, Stubbs & Kramer 2016b); in the Czech Republic and Slovakia, the species appears to occur predominantly in mountainous areas. In Croatia it is known from calcareous seepages depositing tufaceous substrate (Kolcsar et al. 2015); the period of flight is april-october; see table 1 for habitat information of the Norwegian locality(ties)).

Stary and Stubbs, 2015: 333 (most localities have calcareous seepages depositing tufaceous substrate; the species can occur along spring-fed streams associated with seepage complexes, and, in one site, it was abundant beside a large woodland stream well below the source). Spain Habitat. Hancock and Hewitt, 2020: 45-49 (in the Cazorla Parque Natural, Jaen Province, Spain, in june 2019, an area of cliff face was seen covered with a butterwort, Pinguicula vallisneriifolia (Webb), the leaves of which had trapped large numbers of insects, including 19 species of craneflies; the effectiveness of the leaf glandular secretions in relation to immobilising different sizes of flies is discussed; see paper for details, habitat figs). Habitat. Hancock, 2020: 96-97 (on wet rocks near Iznatoraf see habitat photo), also common on tufa rock face and found attached to leaves of butterwort (Pinguicula vallisneriifolia Webb)) (see also Hancock and Hewitt, 2020).
