Your letter to the bugman:  I found this egg mass on an oak leaf in my backyard in September. There are just six eggs laid together on the leaf. I believe they are some kind of insect eggs but I do not know what!

Oak Galls

Dear Hannah,
These are Galls, and they are theoretically not eggs.  Galls are growths on plants (leaves, stems, roots, etc.) that are caused by a variety of reasons, including insects.  Gall Wasps on oaks are quite common and quite diverse.  The Gall is a growth caused by the Wasp larva that then provides a food source for the growing larva.  So the larva does not eat the plant directly, but it does feed on the growth that its presence has caused.  We will attempt to provide you with a less general identification.
