This is how a normal Jersey Tiger Moth should look - I am not sure what to suggest for your poor little visitor @lizzykincaide if it can't fly it seems cruel to leave the poor moth but everything has a purpose and all I can say is to put it in a safe, cool place.
I haven't seen one of these in our garden for decades, but one was feeding on some flowers in the daytime only a couple of weeks ago. If it cannot fly, it should walk on your finger, where you could put it on some nectar-rich flowers. I did the same thing with a Hoverfly that had flown into the house; it
stayed on my finger while I unlocked the door to the garden and put it
on some flowers. Or you can make up a dilute sugar solution on some absorbent material. You should see the Moth's proboscis (tongue) unwind as it drinks.
