A Common Wainscot moth (Mythimna pallens) feeds on a drop of honey.
From Wikipedia (http://en.wikipedia.org/wiki/Common_Wainscot):
The Common Wainscot (Mythimna pallens) is a moth of the family Noctuidae. It is distributed throughout Europe.
As with other "wainscots", this species has buffish-yellow forewings with prominent venation. The Common Wainscot, as the specific name suggests, is very pale, lacking the darker markings shown by most of its relatives. The hindwings are pure white. The wingspan is 32-40 mm. One or two broods are produced each year with adults on the wing at any time from June to October. The moth flies at night and is attracted to light, sugar and various flowers.
