Insect Egg Cases?

Insect Egg Cases?
Opelika, Alabama, USA
November 6, 2004
A friend provided this leaf from a water oak tree layered with what appear to be some type of egg cases. The only other option is some type of a leaf gall or fungal growth. Can anyone provide any insights. Thanks.

Moved from Gall Wasps.

Moved from Galls.

I found an oak leaf today with 21 of these galls. If I collect the leaf will storing it in a plastic container with small air holes be ok? Should I do anything else?

I recommend waiting
until later in the fall, in case they're not mature yet--since we know they stay attached until at least November. Once the leaf is dry, it should be safe to collect it... I'm not sure how late water oak holds onto its leaves, but of course you don't want to wait so long that the leaf disappears. When you do collect the leaf, any sealed container will do--or even a ziploc bag. No need for air holes. The more galls you can find, the better the chance of getting some wasps. And definitely hang onto any wasps you get--a specialist will need to examine specimens to figure out what they are.

I'll keep an eye on them, wait, then hopefully be able to collect them. Thanks!

I'd venture that they are galls. Oaks are host to an incredible variety of galls.

I found these same galls today and was hoping to get an ID on them.
