Source-derived summary

Chalcosyrphus (Xylotomima) libo (Walker, 1849 ), the Long-haired Leafwalker, is an uncommon species of syrphid fly observed in north-central North America. Hoverflies are able to remain nearly motionless in flight. The adults are also known as flower flies for they are commonly found around and on flowers, from which they get both energy-giving nectar and protein-rich pollen.

Distribution

Canada, United States.

Editorial summary

This brief starts where responsible research should: with the source description of “Chalcosyrphus libo” as species of insect. Everything that follows is an evidence route, not borrowed authority.

Editorial reviewUseful for establishing the present vocabulary of the subject while preserving a route back to the evidence on which that vocabulary rests. The current lead gives the account dated anchors—1849—that can be checked directly. The selected authority fields contribute no independent date. The account is most persuasive where Chalcosyrphus, libo and species can be independently traced.
Editorial analysis

Why this record matters

The subject matters to the science & nature register because the source frames it as species of insect. Its deeper value depends on whether names, dates, institutions and citations support that framing.

Evidence profile

The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q13494015. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1849.

Critical limits

Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.

How to read it

Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
