Species text

The species has been recorded from Needs Ore Point, South Hampshire; Colne Point, North Essex; and Dunwich Marshes, East Suffolk, all since 1961. There is also an unconfirmed record from Iken Marsh, East Suffolk. Elsewhere in Europe it is reported from Belgium, Denmark, Sweden, Germany, Austria, the Czech Republic, Hungary and Poland.

Habitat and ecology
Trichoncus hackmani occurs mainly among tide litter and sparse vegetation on shingle. Adults of both sexes have been found from April to June and in September and October, with a male also in July.

This spider has been abundant wherever it has been found, which suggests the possibility of its being under-recorded unlikely.

Disturbance of shingle and destruction of its vegetation by, for example, excessive trampling or use of off-road vehicles. On shingle beds outside nature reserves, holiday developments are also a possible threat.

Management and conservation
Disturbance to shingle due to trampling, off-road vehicles or construction of sea defences should be prevented. Tide litter should be left undisturbed.
