I'm not a gardener by nature, whereas my wife is, but our willow
tree has what looks like a load of dried sap coming out of a spot
on the trunk about 4 feet off the ground, forming a small solid
waterfall effect, and there are several ants crawling around it.
The waterfall is about 4 inches in height.
Maybe it's an internal ant nest? If so, is it bad for the tree,
and how to treat it if it is?
Otherwise, I can't find what it is, so any help welcome.
Is there a good website to ID such problems? All that I have
looked at haven't helped.
A picture might help diagnosis. Don't post it directly here but to
a picture-hosting site such as tinypic http://www.tinypic.com/ and
then post a link here.
I doubt there's an ants' nest in there. Sounds like some sort of
canker, possibly cytospora, and the ants are just feeding on the
sap weeping from the lesion. I don't think there's a cure.
Here are links to the same pictu

Thanks for help.
I don't know what that white patch is. It's just possible it's some
sort of insect attack. It could be a mass of woolly aphid, in which
case a good insecticide spray should deal with them, although the waxy
coat can protect them. Alternatively, just blast them away with a
strong jet from a hose and repeat as necessary. See

It's certainly some aphid-like creature. Yesterday, we gave it a good
hosing, but the little blighters were soon back, and today they have
already made up some of the white stuff again.
Stage 2 will be some kind of insecticide, I think.
