Allium ursinum umbel of six to 20 white flowers only, lacking the bulbils produced by some other "Allium" species such as "Allium vineale" (crow garlic) and "Allium oleraceum" (field garlic). It flowers in the British Isles from April to June, starting before deciduous trees leaf in the spring. The flower stem is triangular in cross-section and the leaves are broadly lanceolate similar to those of the lily of the valley ("Convallaria majalis"). It is native to temperate regions of Europe, from Britain east to the Caucasus. It is common in much of the lowland British Isles with the exception of the far
Berberomeloe majalis are often found close to populations consisting of red-striped specimens, but both morphs seem to be spatially segregated and no mixed series have been found in the field. Entirely black and red-striped specimens of "Berberomeloes majalis" are equally poisonous. The red-striped oil beetle is found in dry places in the mediterranean regions of Spain, Portugal, and also in North Africa, from Morocco to Tunisia.
