About Idaea humiliata (Hufnagel, 1767)
Idaea humiliata (Hufnagel, 1767) has a wingspan of 19–22 millimeters. In the United Kingdom, adult moths have one generation per year that emerges in July, though the flight period can range from June (and rarely late May) to mid-August. The caterpillar stage overwinters. As its common name references, this species was historically found on the Isle of Wight, England, and became extinct there around 1931. A single sighting was recorded in Portsmouth in 1954, but the species is currently considered extirpated from the United Kingdom.
