Your plum may be home to some tent caterpillars: http://www.hiltonpond.org/images/Caterpi... although it sems to me to be a little late in the year for these (from the perspective of where I live, but if you're from the far north, you may still have them). These typically are found on cherries and members of the rose family, and plums are included in this.



The liquid you see may very well be sap. This usually indicates the bresence of a bark-boring insect, and this will often kill your tree by girdling it.
