Donacia piscatrix
Donacia cf. piscatrix is a reed beetle in the subfamily Donaciinae, recorded from Northern Ireland during 2023 coastal habitat surveys. The genus Donacia comprises aquatic leaf beetles associated with emergent vegetation in freshwater and brackish habitats. The specific epithet 'piscatrix' refers to the species' association with water, from Latin 'piscator' meaning fisher. The 'cf.' designation indicates probable but unconfirmed identification, reflecting the taxonomic challenges within this genus.
Donacia rufescens
Donacia rufescens is a species of aquatic leaf beetle in the family Chrysomelidae. Members of the genus Donacia are typically associated with aquatic and semi-aquatic habitats, where they feed on submerged and emergent vegetation. The 'cf.' notation in the record indicates tentative identification based on morphological similarity, pending definitive confirmation. The genus is notable for its ecological specialization on wetland plants and its role as an indicator of habitat quality.
