The Hebrew Character moth flies in spring, as early as
March, and is relatively common over much of UK and Europe. The Hebrew Character moth looks similar to three other, summer-flying, moths - see right/below. Wingspan: 30-35mm. Flies March-April.
For comparison: the Setaceous
, unrelated to the Hebrew Character moth but related to the Double Square-spot below. Flies May to September.
Double Square-spot Moth
The Double Square-spot, bigger than the Hebrew
Character, flies in summer, June-July, and looks almost identical to the Triple-spotted Clay,
Xestia ditrapezium, another summer-flying moth.
