Eat it - Ant farm

The monbretia appear to have become an ant farm since I have been away.  
They are covered in aphids and the ants are milking them for their honeydew. This is apparently a symbiotic relationship benefiting both the ant and the aphids.
The ants are very busy, never still,  so it was hard to get one in good focus using the macro. 
Fun to watch though and a rather tenuous link to the Eat it for today's TinyTuesday!
