Floricomus plumalis
(Crosby, 1905)
Floricomus plumalis is a of sheet-web weaving in the Linyphiidae, first described by Crosby in 1905. It belongs to a of small spiders whose members construct flat, horizontal webs in vegetation. The species has been recorded from both Canada and the United States, though specific details about its biology remain poorly documented.

Identification
Floricomus are small linyphiid , generally measuring 2–4 mm in body length. Distinguishing F. plumalis from requires examination of male and female epigynal structures. The specific epithet 'plumalis' (Latin for 'feathered') may refer to setal ornamentation on the legs or body, though original description details are not widely accessible in modern literature. Identification to species level is not feasible from photographs alone and requires microscopic examination.
Distribution
Recorded from Canada and the United States. Specific provinces and states are not documented in available sources.
Ecological Role
As a member of Linyphiidae, this likely functions as a of small flying and crawling in its web. Sheet-web contribute to regulation of insect in herbaceous and shrub vegetation.
Similar Taxa
- Other Floricomus species share similar small size, web architecture, and general . -level separation requires genitalic examination.
- Other Linyphiidae genera (e.g., Lepthyphantes, Bathyphantes)Many small linyphiids overlap in size and web . Floricomus is distinguished by specific genitalic and somatic characters not visible without magnification.
More Details
Taxonomic note
The Floricomus was established by Crosby & Bishop in 1925. The 'plumalis' was coined by Crosby in 1905 when the was originally described in a different genus (likely Lepthyphantes or a related , though the original combination requires verification). The species epithet suggests or feathery , a character that may aid in identification but has not been emphasized in subsequent literature.
Data limitations
This is rarely encountered in ecological or surveys. The iNaturalist observation count of 2 reflects genuine rarity rather than identification difficulty alone. No species-specific ecological studies have been published.
