About this speciesRecorded altitude range
141m to 141m
DistributionKnown in Britain from two locations in Wales.
Habitat and ecologyIn South Wales a single female was discovered under a rock in woodland, whereas the North Wales female was located within a large slate spoil heap in Snowdonia. On continental Europe Trogloneta granulum is known to inhabit wooded upland block-scree and caves where it constructs a tiny orb-web. Females construct a comparatively large spherical egg-sac.
StatusNationally Rare. Likely to be under-recorded due to its small size and the difficulty in sampling deep scree habitats.
ThreatsSoil-capping or the removal of quarry spoil heaps might threaten this species' specialised habitat.
