Why this record matters
A short description can identify a subject without explaining its stakes. For “Phryganidia californica”, the useful work is to connect “species of insect” to the records capable of establishing context and consequence.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 22, 2026. The linked authority identifier is Q7188161. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1864.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
