Growing Potato

My potatoes are growing rather nicely however in the last couple of days I have noticed that the leaves are looking "skeletal" I did see what I thought was a lady beetle on the leaves- but much bigger. Could this be the culprit? How do I organically control it?

It could be the 28 spotted potato ladybird with out seeing a picture it is hard to say. There are some ladybirds that will eat away at powdery mildew if there is none of that I would most likely say it's the potato lady bird. It will be 6-10mm long, a orange colour with 26-28 dark spots. With the skeletal looking leaves it would be its eggs. There are no chemicals registered for control of the leaf eating ladybirds in home gardens. You will have to remove by hand and squash the larvae and egg clusters. Natural predators that will kill them are parasitic wasp, birds & assassin bugs. So might be wise to encourage these into your yard. Remove any weeds you have in the garden as well. Other plants they will attack are cucumbers, eggplant, pumpkin and tomatoes and some weeds such as nightshades.
