Dasysyrphus occidualis
Locke & Skevington, 2013
Western Brusheye
Dasysyrphus occidualis is a hoverfly described in 2013, distinguished as a western North American representative of the Dasysyrphus . The "Western Brusheye" references its geographic position relative to other members of this group. As with other Dasysyrphus species, it belongs to a genus characterized by distinctive and facial setation patterns. The species remains poorly known due to its recent description and limited observational records.

Identification
Dasysyrphus occidualis can be distinguished from by a combination of western North American distribution and specific morphological traits detailed in the original description (Locke & Skevington, 2013). Within the Dasysyrphus, identification relies heavily on microscopic examination of facial setation, patterns, and male genitalia structure. The specific epithet "occidualis" (meaning western) provides a geographic indicator distinguishing it from eastern and Holarctic relatives.
Distribution
Western North America. The specific epithet and description indicate a western distribution pattern, though precise range boundaries remain undocumented in widely accessible sources.
Ecological Role
As a member of Syrphidae, likely contributes to pollination as an and may function as a or in larval stages, though specific ecological roles for this are unconfirmed.
