October EcoQuest Challenge
Galls are abnormal, vegetative growths that develop on various plant parts in reaction to the stimulus of insects, mites, nematodes, viruses, fungi, or even other plant species. The appearance of a gall is unique to the organism that creates it, and they sport a spectacular variety of shapes, colors, and textures. Oaks are most susceptible to galls and host over 500 gall-forming organisms. Although gall formers have a parasitic relationship with the plants they utilize, galls are rarely a cause for concern, and are not typically detrimental to their host. Galls may be beautiful but they are under-observed on iNaturalist. EcoFlora challenges you to take a closer look at some of your favorite plants (especially oaks!) and see if you can find any signs of galls.

Questers may find these suggestions helpful:
Oak galls that grown on leaves tend to fall off their host leaves this time of year, or come down with the falling leaves, so looking under oaks can be especially fruitful.
For entries, name the host tree/plant if you can, since individual species of gall-inducers have relationships with specific species of plants, and this relationship is helpful for ID.
@matthew_wills Yes! Great advice and information. Adding the name of the host plant is extremely helpful for gall identification.
Additionally, @megachile is a great person to tag for gall ID questions!
