What is the meaning of [Where the bee sucks, there suck I]

From Shakespeare’s The Tempest, 1610:

ARIEL [sings]

Where the bee sucks, there suck I:
In a cowslip’s bell I lie;
There I couch when owls do cry.
On the bat’s back I do fly
After summer merrily.
Merrily, merrily shall I live now
Under the blossom that hangs on the bough.
