|The huge genus Hieracium
(Hawkweed) comprises a myriad of microspecies, many of
which feature beautiful UV patterns. This is a
microspecies of the Pilosella subgenus, which
has a variegated UV pattern, comprising a patchwork of UV
absorbing and reflecting areas of the flower head.
The yellow flower heads are frequently visited by a number of insects, but since these Hawkweed species all are apomictic and able to set seeds without pollination, the need for UV advertising is slightly enigmatic.
