Assessment Notes

Taxonomic notes

Why suggested for a Global Red List Assessment?

There is sufficient evidence to indicate that this species should be evaluated as Least Concern

Geographic range

Mainly a northern temperate species, possibly also boreal. AFRICA: South Africa. ASIA: Georgia, Japan, Kazakhstan (Aktyubinskaya oblast), Pakistan. EUROPE: Belarus, Belgium, Finland, France, Germany, Italy, Lithuania, Luxembourg, Netherlands, Norway, Poland, Sweden, Switzerland, Ukraine, UK, former Czechoslovakia, former Yugoslavia. NORTH AMERICA: Canada, USA (New Jersey, North Dakota, South Dakota, Vermont, Virginia).

Population and Trends

More than 200 records since at least 1852 and up to at least January 2008. Observed in every month of the year except February and November. Trends not known. Estimated extent of occurrence [calculated using http://geocat.kew.org]. 14•7 million km2 (Africa: insufficient data; Asia: 9•2 million km2; Europe: 3•2 million km2; North America: 1•8 million km2). Estimated area of occupancy [calculated using http://geocat.kew.org]. About 108 km2. The method for estimating area of occupancy has produced an artificially low figure. The species is likely to be under-recorded particularly in recent years because of the small and declining numbers of people with the skills to search for and identify it. Many of the plants with which it is associated are common and widespread species.

Population Trend: Uncertain
