#GallWeek25

Galls! galls! galls!
I am embracing gall week over on iNaturalist and spending time going on very slow walks looking at every potential gall host.
Oaks are a popular host - previous gall weeks meant I learned about some of the galls on Oak.
Some of the many and various galls found today shown here.
More info and names (as far as I know them) in the alt-text
*edit typos - spangle galls
#galls #GallWeek25

A close cropped photo of the end of an oak branch. At least three different galls are visible. The green ball is an oak marble gall (I think) the brown rosette in the centre is an oak artichoke gall and the small discs on the back of a leaf on the right are silk-button spangle galls (brilliant name)

Two knopper galls, one is obviously growing out of an acorn, the other is just a rough pointy mass of plant material.
There is a thin branch across the picture, and out of focus oak leaves behind.

Close up of the silk-button spangle galls. So shiny! Like little donuts on the back of the oak leaf.
You can see the hand holding the leaf to turn it to take the photo

A cluster of three Cola nut galls on an oak twig. They look like brown wooden balls. More oak leaves make up the rest of the picture

I don't want to name names but apparently some of you did not go out and take photographs of galls yesterday. #GallWeek25 #GallWeek2025 #GallWeek #gall #galls #insects #inaturalist #entomology #nature #cynipidae https://www.inaturalist.org/projects/gall-week-september-2025
