Culiseta annulata
species of insect

Culiseta annulata is a species of mosquito in the family Culicidae. It is found in the Palearctic.
Ecology
Culiseta annulata overwinters in its adult stage. In Northern Europe, females of this species are found in caves from autumn to early spring together with females of genus Culex (Culex pipiens, Culex torrentium, and Culex territans).
In the Czech Republic the most frequent animals bitten by it are european fallow deer and red deer, however it also bites humans, sheep, other deer and pigs.
On 16 October 2025 it became the first mosquito species with both male and females identified in Iceland. None were found over the summer of 2026.
Vector potential
Japanese encephalitis virus RNA has been detected in its saliva and it is a competent if inefficient vector of Tahyna virus.
Begin with the source’s own compact description: “Culiseta annulata” is species of insect. The dossier treats that line as a proposition to test through Culiseta, annulata and species, not as a finished interpretation.
Why this record matters
The phrase “species of insect” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Sep 19, 2026. The linked authority identifier is Q2153608. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2025 and 2026.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
