Your letter to the bugman: Hello, I was walking today (May 18) and found this unusual growth on a small tree sapling off of the neighborhood trail. I’ve searched but have only found one image even close and it was a silk moth chrysalis.

Dear N. Celata,
Your sapling appears to be a young Oak and this is a Gall, a growth that appears on plants and is often caused by an insect. Oaks are hosts to many different Gall Wasps that produce Galls. Based on images posted to Discover Life, we believe this is an Oak Apple Gall, Amphibolips confluenta.
