Ancyloscelis males have long, hooked legs. Specialist pollinators of the morning glory family.
Solitary nest on hard, clay soil. She was actively excavating the nest and using her hind legs to throw soil balls 6-10 inches away. Videos posted at:

This is a male Hylaeus (masked bee), measuring 7 mm, found on Pyracantha. This largely black bee has yellow markings on the face, pronotal collar and pronotal lobes. The first segment of the bee’s abdomen (T1 and S1) is mostly red; the rest of the abdomen is black. The lower legs (tarsi, basitarsi and tibiae) are mostly yellow. The hind tibiae have pale orange-brown spots on the inner surfaces. The bee's upper legs are black and reddish. The apical (rear) half of each of the bee's forewings is dark.
This male was found on the same Pyracantha bush as the female shown here: https://www.inaturalist.org/observations/206495084
I think this is just an especially threadbare vicina. I did have the thought, when I saw her, “What are you doing so far out of the neighborhood?” They seem like city bees to me, but that’s probably largely due to their common name.
Confirmed by K.Wright. Gestalt wise, looks similar to comptoides, but pitting of T2 is too sparse and not coarse enough.

This 11 mm male resin bee was found with several other identical males on tarflower (Bejaria racemosa), a plant with fragrant, large white blossoms. Also called flycatcher, tarflower has sticky petals and buds that trap flies and other insects (although it doesn’t digest them like truly “carnivorous” or insectivorous plants). The male bee shown here got stuck on one of the buds and spent a lot of time tugging itself free. Afterwards though, it returned to the tarflower and hung around with the other males, which appeared to be looking for nectar. Some other Megachile (e.g., M. pseudobrevis, M. mendica and M. petulans) are known to visit tarflower. So do honey bees, some sweat bees, & bumble bees, despite the “flycatcher” capability.
About this ID -- the Discover Life database notes that Megachile georgica “males have a large dark brown spot on the inside face of the tarsal segment just below the front basitarsal segment; this appears to be unique to this species” (https://www.discoverlife.org/20/q?search=Megachile+georgica). Other known Megachile (Chelostomoides) of Florida include Megachile campanulae (male entirely black / doesn’t have red forelegs); M. rugifrons (front tibiae of males bright yellow & mandibles 8-dentate); and Megachile exilis parexilis. In addition to the dark spot on the tarsal segment, this bee's size and the evenly distributed & dense long white hairs all along the cheek point away from Megachile exilis. The male Megachile exilis also lacks the two short narrow stripes of pale hair on the front of the scutum.
About two weeks after the male bee shown here was found, female Megachile georgica emerged in large numbers in the same area, to gather pollen from tarflower. A female is shown here: https://www.inaturalist.org/observations/224177190
Neither of these two guys had any intention of letting me see their S2 projection or T7 during their impassioned tussle.

pointed projection on S2 and flattened antennae tips on male?
A juvenile P. audex? A split-second later, spider with bee toppled to the ground. Bee was an unlucky male Andrena, subgenus Melandrena.

On blackberry.
I’ve seen as many as six on the same Rubus at once. There’s at least 1/4 acre of rubus alone on which to feed. So this species must be friendly since they’re not social bees.
I think most likely a masked bee but couldn’t get a great photo in the light. The bottom part was a reddish brown that really stood out against the white flowers.

Taken with camera without GPS - approximate location. In the West Tract of the WMA near the Henry Currington Road entrance (or so.)
With leaves from nearby Crataegus shrub in shrubby grassland mostly dominated by cool-season exotics. Entered and left nest in ground burrow in sandy soil.
Today the bats didn't come out until 16 minutes after sunset, and it took even longer for them to get close. That means no color in these photos, unfortunately. Perhaps this gives a better idea of snout/ear shape though? Presumably the same species as https://www.inaturalist.org/observations/202484027
