This usually annual species is found in shallow water and on the muddy edges of rivers, streams, ponds and lakes, in dune-slacks, and in clay-, gravel- and chalk-pits. Although often found with V. anagallis-aquatica, its habitats are more restricted, being more frequent on the muddy edges of standing waters. Lowland.
The distribution of V. catenata has changed little since the 1962 Atlas, but it is now much better recorded.
