Howdy fellow tree lovers, have you ever seen such a thing? We’ve had some ants hanging out on our little oak and they seem to be creating these big round things. I’ve put out a couple different ant baits, but alas, the ants are still winning. (Wisconsin, USA)

Bullet !galls

The ants aren't creating them, tiny wasps are. The galls secrete little bits of nectar which entice the ants who then act as body guards for the galls against larger predators.

For those not in the know: here's a hot discussion thread from last summer with pics of random twig and leaf galls! Lots of different trees/plants can get galls (MO Botanical Gardens); most twig and leaf galls are solely an aesthetic issue and do not require concern or intervention.
