Moved from Ants.

These ants weren't traveling in an organized line. I was photographing Camponotus when I saw a big group(50+ widely spaced individuals; looked like a loose herd as opposed to column spread over a 2x5 foot area) heading north into a manzanita, by the time I got my camera ready they had all pretty much exited the clearing. About 15 minutes later, I noticed them coming back my way still as a widely spaced group, the return group featured many somewhat injured looking workers along with workers carrying pupae. I tracked them to the manzanita bush where they would go into the leaf litter and emerge with larvae, there were over a hundred enraged carpenter ants present searching through the litter and trying to catch and kill the amazons. Further back in the bush there were a few Formica lasioides so I'm thinking these were the larvae they were taking (the larvae also looked too small to belong to the attacking Camponotus). There were no F. moki in the vicinity.
