The distribution area of Oligotricha striata extends over
whole Europe (except for the Iberian Peninsula) eastwards to NW-
The aquatic stages inhabit pools and ditches in peat bogs and moors,
preferably in mountainous regions, and can be found in stagnant
or slowly flowing, acidic water (Botosaneanu & Malicky 1978,
Waringer & Graf 1997, Wallace et al. 2003).
Larvae are shredders and carnivorous (Graf et al. 2002). According
to Majecki & Malysz (1992, cited by Waringer & Graf 1997)
they feed on spawn clumps of Rana temporaria.
Adults are on the wing from March to July (Waringer & Graf 1997).
