Paul Allen's flower fly
species of insect
Paul Allen's flower fly (Eristalis alleni) is a flower fly found only in Costa Rican forests in the central highlands. It was named after Paul Allen. Another fly was also named after Allen's associate Bill Gates, Bill Gates' flower fly (Eristalis gatesi).
It is similar in appearance to Eristalis circe Williston, 1891 and Eristalis persa Williston, 1891, but has different leg colouration.
Biology
Little is known of its biology, but most adults are found in association with flowers in the genus Senecio.
Begin with the source’s own compact description: “Paul Allen's flower fly” is species of insect. The dossier treats that line as a proposition to test through Paul, Allen's and flower, not as a finished interpretation.
Why this record matters
The phrase “species of insect” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
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 Dec 18, 2025. The linked authority identifier is Q1953082. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1891.
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.
