Where the White Bryony grows, you can also find the Bryony Ladybird (Henosepilachna argus). It lives on the poisonous climbing plants and feeds on their leaves. It is also said to colonise other cucurbits, but I have never seen it in the garden on zucchini or cucumber plants.

The Bryony Ladybird likes it warm and is found in central and southern Europe, as far as North Africa and temperate Asia. Here in southern Germany it is common, with several beetles living on almost every white bryony.
It is easily distinguished from other native ladybirds by its orange head shield.
Henosepilachna argus grows to between 6 and 8 millimetres in length.
