Dicheirotrichus gustavi is a ground beetle which emerges from cracks or holes to feed on tidal salt marshes after dusk. Despite living in a coastal environment, it has no cycle of behaviour linked to the tides, simply scurrying for dry land when caught by the approaching sea.[1] It will eat the larvae of another intertidal beetle, Bledius spectabilis, if they are left unprotected by the adult.[2]
