Catalpa Sphinx?

I noticed a unch of tiny black worms with yellow sides eating my onions leaves. They were all wilting badly and I couldnt figure out why until I saw these. I think they are killing my garden. MY best guess searching google is that it is a Catalpa Sphinx variety. How do I get rid of them? Water spray doesnt dislodge them. Poking them with a stick trying to squish them results in them burrowing under the dirt and coming back.

They are most likely onion maggots.

Catalpa Sphinx only eat the leaves of the Catalpa tree.

I don't think so. Google says magots like cool wet conditions. It is very hot and dry here. The soil around the onions dries up an hour after watering. The pictures also don't look anything like these guys.
