Abstract

Multispecies aggregative spider webs consisting mainly of linyphiids are reported from the municipality of Vörå in Finland. The dominant species were Erigone atra Blackwall, 1833 and Savignia frontata Blackwall, 1833 and most of these represented by males. The spider assemblage consisted of at least 13 species altogether. The reason for the aggregations was habitat disturbance caused by flooded cultivated fields.
