> Is there an actual study that shows periodic exposure to very small
amounts on neonicotinoids results in cumulative effects?

Not that I've seen.  Suchail (2001 and 2004) detailed the rapid metabolism
and excretion, and Cresswell (2013), feeding bees continuous doses, found
that workers can eliminate nearly half the LD50 every day, and appeared to
suffer no loss of locomotory behavior over the course of the trial,
suggesting no cumulative effects.
