A swarm of ladybugs 80 miles x 80 miles and flying at 5000-9000 feet altitude was picked up on weather radar:

May be some great photo ops when they land. I know in AZ and here in NM that they gather in large masses.

I am assuming these are all alien species? I hardly see any native species where I live anymore.

Wow! This is cool stuff. I hate to ask, but do they do any damage? We have them occasionally in the crevices of our windows here in upstate NY, but not in those numbers.

They are desirable in gardens to eat aphids. They are actually sold for that very purpose.

Ladybugs migrate to South America in our  NA fall/winter and return in spring, according to one source online. I don’t know if that’s true, but they are native species along with Australian imports.

Don't know which these were but there is an invasive species of Ladybugs here in the east anyway. It would be nice if these were native.
