What this means
The species has been recorded in the listed places in the stated source universe. Peak month: September.
9 months reach at least 10% of the peak facet count.
What this does not mean
repeated describes the record pattern, not a formal range, residency, abundance or conservation assessment.
A single record remains evidence of a recording, not proof that a population lives there.

When it is recorded
JFMAMJJASOND
Peak month: September. Records cluster in the months an animal is present and being looked for, so a summer peak can reflect observer effort as much as the animal.
Records over time
18572026
Recording effort has risen steeply almost everywhere since the 1990s, so a rising line usually shows more observers rather than more animals.

Repeated records across many years and months. This is inferred from how many years and months the animal appears in, not from a range map — treat it as evidence, not a formal assessment.
