Ethmia pyrausta

Ethmia pyrausta is a moth of the family Depressariidae. It is found in northern Scandinavia and adjacent Russia, as well as in China and Mongolia.[1] The species is sometimes referred to as being "mythical", because it is so rarely encountered outside its remote native range. It is a rare migrant to the UK[2] and also found occasionally in other areas in Northern Europe.[1]

"Tinea nigrella" redirects here. As invalidly described by Hübner in or around 1805, this refers to Elachista freyerella.

Description and ecology

It has black wings and a "hairy" orange body with a wingspan of 17–23 mm (0.67–0.91 in).

Larva live in a thin silky spin between the leaves and flowers of Thalictrum aquilegiifolium, Thalictrum simplex and Thalictrum flavum. There is evidence of breeding in the UK, with larvae found in Easter Ross in 2014.[3]

Sightings in the UK

They were first recorded in the Shin Valley in 1853. Two were found in 1996 on the top of Glas Maol in the Grampians with a further two found nearby.

In June 2008 an adult Ethmia pyrausta moth was discovered in Easter Ross, by Andy Scott and Margaret Currie after finding it trapped in a spider web.[4]

gollark: It has a surprisingly good algorithm for guessing whether people *intended* to blaspheme potatOS.
