What symbiotic bugs would those be? [...]

Sap suckers:

``Some ant species, such as the common Black garden ants
(Lasius niger) found in the UK, farm aphids. They have
aphid livestock which they transport between plants and
protect from enemies in return for a sugary substance
called honeydew, excreted from the aphids as they suck
on plant sap.''


The aphids bite into the plant and lock on, there is then a continuous flow
of honey dew from their rear end, the ant take advantage of this free food
fountain! If the flow stops they tickle the ant's rear end to get it going
