Identification
Wulfila tantillus can be distinguished from web-building by its lack of web construction for capture. As a member of the Anyphaenidae , it likely exhibits the pale, somewhat translucent coloration typical of ghost spiders. -level identification requires examination of genitalic structures and other microscopic features; the specific epithet 'tantillus' (Latin for 'so small') suggests diminutive size. Differentiation from other Wulfila species and anyphaenid requires taxonomic knowledge.

Habitat
Documented from Panama and the United States. Observations of Wulfila in urban ecological studies indicate association with tree , particularly in -infested urban trees. The has been collected in association with in urban landscapes.
Distribution
Panama; United States. GBIF records indicate distribution from USA to Panama, with specific locality records from Panama.
Behavior
Active hunting that does not construct webs for capture. Documented as part of the hunting spider in urban tree studies, where spiders in this were observed moving between tree canopies and understory shrubs.
Ecological Role
in urban . Observations of Wulfila in -infested urban trees suggest they may contribute to predator that respond to . The presence of active hunting spiders like Wulfila in urban tree has been associated with enhanced removal in nearby shrubs, indicating potential for services in urban landscapes.
Human Relevance
Has been studied as part of in urban pest management research. -infested trees that support Wulfila and other hunting may provide associational pest to nearby landscape plants through movement. This suggests potential value in strategies in urban horticulture.
Similar Taxa

- Other active hunting spiders (e.g., Oxyopidae, Salticidae, Clubionidae)Share the active hunting characteristic of not constructing capture webs, but differ in -level morphological features such as arrangement, structure, and cheliceral .
- Wulfila other species share -level characteristics; boundaries in Wulfila are narrow and require detailed taxonomic examination.

Taxonomic note
The specific epithet 'tantillus' is Latin for 'so small' or 'very little', presumably referring to the small body size of this relative to .
Urban ecology context
Wulfila were specifically mentioned in research on -infested urban trees at North Carolina State University, where they were photographed by Matt Bertone as representatives of the active hunting spider . This research documented that scale-infested urban trees support higher abundance of active hunting spiders compared to uninfested trees.
