Clifden Nonpareil Catocala fraxini (2451, 72.076) is an immigrant and transitory resident. They were resident in Kent during the mid 20th century.
From earliest records to 1964 they were not recorded annually and when seen were usually in single figures. The exception was 1953 when there were 18 records. There are no reports from 1965 to 1989. As can be seen from the graph below from 1990 there were low numbers, but it did not become annual until 2008. At least 1 has been recorded every year since then with a peak of 13 in 2010.
There has only been one record in West Kent since 1920 which was at Orpington in 2008.
Nationally exceptional years are often associated with the arrival of Camberwell Beauty butterflies, Great Brocade moths and in 1995 with Barred Warblers. This and the national distribution suggest that the main source is eastern Europe, Scandinavia or Siberia.
They are recorded at rest by day on tree trunks and walls and are strongly attracted to sugar. Usually only caught in light traps in small numbers.
