Found another tiny sweat bee, this time on asclepias that we planted for butterflies. Curled up, I think less than 3mm, but stretched out like this, which she only did when reaching for another flower, I would guess 4mm, possibly 5. I didn't get a ruler to check. The flower was blowing in the wind, so I just kept shooting, hoping to get a few in focus. I kept it up until a honeybee landed on the same flower, scaring her off. The honeybee looked gargantuan by comparison.
C&C welcome, as always.
