Wulfila albens

(Hentz, 1847)

ghost spider

Wulfila albens is a of ghost spider in the Anyphaenidae, first described by Hentz in 1847. It is found in the United States and Jamaica. As an active hunting spider, it does not construct webs to capture prey. The species has been documented as part of natural enemy in urban landscapes, particularly in association with -infested trees.

Identification

Wulfila albens can be distinguished from web-building spiders by its active hunting —ghost spiders in the Anyphaenidae do not construct capture webs. Within the Wulfila, identification to level requires examination of morphological characters not detailed in available sources. The family Anyphaenidae is characterized by the presence of a tracheal positioned near the , though this feature requires microscopic examination.

Habitat

Documented from urban tree and associated shrubs, particularly in landscapes with insect . Has been collected from holly shrubs (Ilex ) growing beneath infested trees.

Distribution

United States; Jamaica

Behavior

Active hunting spider that does not construct webs for prey capture. Documented as part of spider guilds associated with -infested urban trees, where increased abundance has been observed in shrubs below infested trees compared to uninfested trees.

Ecological Role

in urban . Contributes to services in landscape , with documented association between -infested trees and increased abundance of active hunting spiders including Wulfila in understory vegetation.

Human Relevance

Beneficial in urban and landscape pest management. Research indicates that tolerating scale insects on urban trees can support of active hunting spiders like Wulfila, which may enhance of pests in nearby plants.

Conservation ecology

Research by Wilson and Frank (NC State University) documented that Wulfila spiders were more abundant in holly shrubs beneath -infested trees compared to shrubs under uninfested trees, suggesting that scale insect can enhance quality for this active hunting guild.
