If I'm understanding what I'm seeing, the first photo is of an oak (Quercus kelloggii) stem, ruptured as wasp larvae
develop.

The second photo is of an individual wasp larval chamber. (These are still attached to the stem in the first photo).

Such amazing galls!

Description

A male Pacific Spiketail preys on yellowjackets and is in turn attacked by female yellowjackets, which causes some annoyance but does not change the outcome.

I have found males of this species in chaparral, far from water; in our area it seems to prey exclusively on yellowjackets.
