I found this weird growth on the arrowwood in my backyard. At first I thought it was a gall. Closer inspectno showed it was constructed from small bits of detritus along a stem.

I aso discovered that it's occupied by ants! I don't think they built it. They were tending aphids on the stem within the shlter of the nest.
