I'll have to come up with a more fleshed out list, but at first blush...
Tithonia (Mexican sunflower) - blooms until frost and everything loves it... Bees, butterflies, hummingbirds, etc. I will never be without this plant again.
Swamp milkweed
Common milkweed
Butterfly weed
Speedwell's... Honestly every member of this genus that I've seen
Rudbeckias
Echinaceas
Delphinium
Huecheras / Coral bells - don't overlook these. Most native bees are quite small and Huecheras seem to only draw them here.
Cannas - confirmed, great for certain bees and hummingbirds
Swamp hibiscus, a.k.a. Swamp Rose Mallow - love watching hibiscus bee males patiently awaiting female arrivals in the flowers
Almost any Helianthus spp.
Monardas
Sedums - any of the tall showy types. I have a lot of Autumn Fire and Autumn Joy but do have a couple of others. All are bee and butterfly magnets.
Echeverias - we found out by accident that hummingbirds like them... So we now have more!
Zinnias
Cosmos
