Do ladybugs eat sugar or bread?

No because my ladybug got out and when I found her she was nearly dead so I gave her some sugar and water and put it in front of her and she didn't eat it ,but I looked up that ladybugs eat half a raisin a day so put one raisin and feed your ladybug for two days I didn't feed my ladybug a raisin because I didn't have any at the time. olivia 2013
