Large yellow underwing
Noctua pronuba
47.3099, -122.319
Field Notes
Description:
This is a quite large and heavy moth with a wingspan of 50–60 mm. The forewings are quite variable from light brown to almost black. The darker individuals often have a pale streak along the costa. The hindwings are bright orange-yellow with a black sub-terminal band. As with other Noctua species (and numerous other insects), this contrast of bland-on-land and bright-in-flight is used to confuse potential predators. This species flies at night from July to September [1] and is attracted to light, sometimes in huge numbers. It will also visit flowers such as Buddleia, ragwort, and red valerian.-Wikipedia.
Habitat:
Spotted in backyard at night.
Notes:
It is also present in Europe, North Africa, Canary Islands, Middle East, Turkey, Iraq, Iran, Afghanistan, northwest India, Russia, Novosibirsk Oblast, Caucasus, Transcaucasia and Central Asia. It was introduced into North America at Nova Scotia. Since then it has increased its range considerably and has been recorded for Maine in 1985, and then spread throughout the northeast from Vermont and Massachusetts (1989) to New Hampshire (1990), New York, Maryland (1992), and Connecticut (1993). It was first recorded in Pennsylvania in 1998, North Carolina (1997) and west to Colorado (1999), Wyoming (2000), California (2001), British Columbia (2002) and Alaska (2005) and Ontario (2017).
