robinia tree death and ? pest invasion
One of our robinia trees had less leaves than usual last year, this year it is dead. I have started to lop the branches in preparation for removal of the tree. I noticed that the tree has masses of clusters of small wine red balls (eggs!), each individual ball presently being smaller than pin-head size. These are mainly situated on the underside of branch junctions, but also surrounding dead 'buds' and even in gaps where the bark has split.
Any help in identifying this would be much appreciated.
