Ivy blossom offers a useful source of nectar for hungry moths.
A dusk visit with a torch may reveal a surprising number of species.
Looking at any flowering plants may produce feeding moths. The
spectacular Convolvulus Hawk-moth is particularly attracted to the
flowers of Tobacco Plant (Nicotiana) at dusk, where it hovers in
front of the flower and uses its 14cm proboscis like a straw to
drink the nectar.
