What this means
The species has been recorded in the listed places in the stated source universe. Peak month: July.
12 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: July. 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
19332025
Recording effort has risen steeply almost everywhere since the 1990s, so a rising line usually shows more observers rather than more animals.
