Erophilo-Arabidopsietum is a weed or ruderal community of vernal ephemeral therophytes developing in disturbed places on slightly acidic soils. It occurs in winter-cereal fields, on recent fallows, near roads or railways or on disturbed sites in grasslands. In late May it is replaced by other associations of the alliances Scleranthion annui or Oxalidion fontanae on arable land or by vegetation of taller annual therophytes in ruderal habitats. In the Czech Republic it is widespread at middle altitudes.
