Assessment Notes

Justification

This is a widespread, gregarious species of eastern North America. It is not expected to face any significant threats and so is assessed as Least Concern.

---

Geographic range

First described from Nova Scotia, Canada (Petersen 1975), this species occurs in the eastern part of North America, following the Appalachian Mountains southwards (GBIF 2023, Hopping 2023, iNaturalist 2023). A record listing as occurring in Czechia in GBIF (2023) is assumed to be in error.

---

Population and Trends

The overall population size and trend are not known, but with its wide distribution it is unlikely to have a small population size, especially as it is described as gregarious (Hopping 2023).

Population Trend: Unknown

---

Habitat and Ecology

The type collection was made in boreal forest, with the species noted to be from coniferous/mixed forest (Petersen 1975). With its known geographic range it is presumed to not be restricted to boreal forest, as it occurs down into the temperate zone.

---

Threats

While the species may face some localised threats, it is unlikely to face any significant threats that impact it at the population level.

---

Conservation Actions

Further research to ascertain the full distribution, population size and trend would be useful, as well as to investigate if it is associated with any specific plant species.
