Species Profile
The filmy dome spider is a sheet weaver: a spider in the family Linyphiidae with a holarctic distribution. These spiders construct a dome of fine spider silk and hang upside-down under it, waiting for their prey. It is a preferential host for the kleptoparasitic Argyrodes trigonum.
The Filmy Dome Spider (Neriene radiata) faces severe threats primarily from habitat destruction and fragmentation of its specialized wetland and forest edge environments. Climate change and human development pressures continue to reduce the availability of suitable microhabitats required for this species' survival. The spider's extremely limited range and specific ecological requirements make it particularly vulnerable to environmental changes.
