The species has been recorded in the listed places in the stated source universe. Peak month: April.

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: April. 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
18632026
Recording effort has risen steeply almost everywhere since the 1990s, so a rising line usually shows more observers rather than more animals.
