No you have nothing to worry about. I have lady bugs and butterflies like crazy.

Ladybugs and their larvae will eat almost any small, soft-bodied insect such as aphids. It MIGHT include a small newly hatched caterpillar if they found it ... but they aren't going to annihilate your butterflies and caterpillars.

Aphids are their preferred prey because they are easy to catch.

The Lady Beetle, Lady Bug, "Coccineludae", or little red sphere, and its larva will eat many soft bodied insects including Aphids, Scale, Mealy Bugs, Leaf Hoppers, Mites, as well as pollen if other food sources are not available which is why all gardens should flowers included.

Like the list of "target" insects on many insecticides you will not see a list of otherwise beneficial insects predators may munch on, but most often that is not a problem.
