More Details
Taxonomic placement
Nausigaster geminata belongs to the tribe Merodontini within the Eristalinae of hoverflies. The Nausigaster is part of a diverse group of syrphids commonly known as drone flies or rat-tailed maggots, though this particular lacks the association with those groups.
Data limitations
Available information for this is extremely limited. The Catalogue of Life and GBIF confirm its accepted taxonomic status, but biological and ecological data are essentially absent from major entomological databases and literature sources. The sparse iNaturalist records (4 observations) suggest it is either genuinely rare, under-collected, or difficult to identify in the field.
