You are almost certainly correct in your assumption that Lady Bug larvae
would make good fish food, however the main problem I see with culturing
of these beetles is that both the adults and the larvae are predacious,
feeding primarily on aphids, whereas the mealworms need only some
sort of grain for food.
In fact Lady Bugs are highly prized by gardeners since they are so
effective in protecting plants from infestation by aphids, and are widely
sold for this purpose.
So if you could provide a constant source of aphids for your ladybugs you
would probably be ok, but in that case you might as well just feed the
aphids (which are likely pretty easy to raise) to your fish! :)
Anyway, its seems that you are a lucky guy to have so many lady bugs in
your area, at least from a gardening point of view, since they so helpful
in removing unwanted garden pests!
