Cornish Red Data (2009)

The descriptive text, below the map, is from the Cornish Red Data Book (2009). The map on this web page depicts the organisms distribution and shows the records made pre-2000 and those made since.

Lasius psammophilus

Range & Status

In Britain mainly south and south-eastern England, with records from north Wales.

Regional Distribution

Recorded reliably in Cornwall only from Predannack by Paul Gainey, but widely recorded on the Isles of Scilly. This species is very difficult to separate from Lasius alienus , from which it has only recently been separated, and from which it can only be distinguished by microscopic examination, preferably checking a series of specimens.

Habitat & Ecology

Occurs on dry heaths, also possibly sandy areas.


No known threats.
