Ladybirds don't just eat garden pests: they eat plants too. Specifically, ladybirds like to munch on pollen if they can't get a juicy aphid to snack on.

They munch on spider mites and mealy insects, too. Plants that attract aphids include bronze fennel and vegetables, such as potatoes and cabbage. You'll find ladybug eggs in these plants. The ladybirds lay their eggs here so that when the eggs hatch the young larvae will have a ready source of food: aphids!
Different Flavors for Different Ladybugs
There are more than one kind of ladybug and each one has its own preferences for what will attract it to a garden. There is a lot of overlap; however, the harmonia ladybug and C7 both like early blooming flowering plants like cilantro and aphid bait plants. Hippodamia, on the other hand, is a species of ladybug that likes soft-bodied insects, most of which feast on vegetables. For this reason, hippodamia likes anything from the wild carrot family, including fennel and cilantro, but also yarrow and lambsquarters.
