Gall Week 2021!

Dear gall enthusiasts -
Since there is spider week, Cal Coast week, and taco day, we need to have Gall Week! I thought it would be fun to try and document many galls during one week of fall. I think the first week of October could be good, when there should still be plenty of gall in the Bay Area. Are you in?
I will create an iNat project, and I would also like to do some outreach, to tell more people how awesome galls are.
If anyone is interested, we could plan some outings together. I thought it could be nice exploring new places less covered on iNat, target specific gall species, or look for less observed host plants.
Please let me know what you think, if you like (or dislike) the idea, if you’ve got any ideas for locations, gall species, or host species of interest, or if you’ve got suggestions for the t-shirt design :)
Happy fall!

"I Wish They All Could be California Galls" Week"

I would like to participate. If local (south Bay Area) outings are planned, I'd like to participate if it's practical.

發佈由 teellbee 約 2 年 前

@chyroptera Here is a list of print-on-demand companies.
If someone submits a design and sends the link, we can buy our own shirts of the same design. Might even be able to put the image on other products.

Glad it's going to be national--I'll be in Arizona that week.

發佈由 milliebasden 約 2 年 前

Sounds like a great idea!

發佈由 kdff 約 2 年 前

So glad to read all the responses! I'm glad to see I'm not the only one excited about galls :)
Here's the project page I just created - let me know if I should make any changes, join in, and spread the word!

發佈由 merav 約 2 年 前

@debkccb - please do help us advertise! I'll also share on later today.
@chyroptera - thanks for the link. I would love to make a t-shirt. I don't think Taco Day has one :)

發佈由 merav 約 2 年 前

@ceiseman - I hope you can join Gall Week! also if you could spread the word on your gall projects?

發佈由 merav 約 2 年 前

I love the idea and I am ALL IN assuming I won't be in Utah (maybe you could include Utah in that project!

發佈由 leslie_flint 約 2 年 前

oops now I see the everywhere is included! Yay!

發佈由 leslie_flint 約 2 年 前

Please read -
I got all excited and created the project this morning as a regular project, but I'm afraid that won't work well. Coming 10/2, it will aggregate observations of all taxa worldwide! That would be pretty incredible, but not exactly what I was aiming for.
So I created an old fashioned project, were we'll have to manually add observations of our beautiful galls during Gall Week -
I think this is the best way to go, please correct me if I'm wrong! @tiwane

發佈由 merav 約 2 年 前

No, I think this is the best option.

Now that we are all celebrating Gall Week (not just California), please pass the word:

BTW, next year the list of California-related events will also include California Biodiversity Day, which a lot of us missed. See]

發佈由 nancyasquith 約 2 年 前

Sounds great! I'll be able to look for some more galls this weekend. Unfortunately I don't know of any gall enthusiasts in my area (Southern OH).

發佈由 kemper 約 2 年 前

@kemper - you can be the first, and maybe next year others will follow!

發佈由 merav 約 2 年 前

You're making me wish I were in CA and not NJ. But I'll see what I can do from my end.

發佈由 srall 約 2 年 前

I'm with @srall; Massachusetts is great and full of galls (and we can claim @ceiseman), but I would LOVE to be in California the first week of October!

發佈由 lynnharper 約 2 年 前

Cool! Looking forward to participating from DC :-)

發佈由 carrieseltzer 約 2 年 前

I'm adding a promotional blurb to the gall podcast episode show notes that I just released! And will definitely participate as much as time allows.

發佈由 naturesarchive 約 2 年 前

Yesss this is an excellent plan! I’ll be joining virtually from the DC area as well!

發佈由 esummerbell 約 2 年 前

Great idea! Hopefully the oaks here in Manitoba hold on to their leaves long enough for this....

發佈由 friesen5000 約 2 年 前

Perhaps of interest @marykrieger @brguinn @louisnastasi

發佈由 friesen5000 約 2 年 前

This is awesome! I'll spread the word down here in San Diego! @milliebasden thanks for covering AZ for us that week :)

發佈由 madily 約 2 年 前

Thanks @kemper for the heads up! I will definitely try to find as many galls as possible. We happen to have a bioblitz in east Texas during that time so hopefully there will be some new galls added to the Texas observations.


發佈由 annikaml 約 2 年 前

@friesen5000 leaves on the ground mean that we can spot the galls on the stems :)

發佈由 marykrieger 約 2 年 前

As we go nationwide, how about "The Galls Next Door" for the slogan?

發佈由 gyrrlfalcon 約 2 年 前

A gall week,,, in october? Sometimes I forget that other people live in places without winter. I'll try my best, but october won't leave that many leaves out and about to find galls on

發佈由 mws 約 2 年 前

Ah! More evidence that all knowledge is local!
In California, late September-early October is the best galling season.
So sorry about this phenomenon you call "winter."

發佈由 gyrrlfalcon 約 2 年 前

October is a pretty good gall season for us in Southern Ohio too. November too, a lot of leaves with galls on them begin to fall to the ground.

發佈由 kemper 約 2 年 前

Looking forward to it! Everyone I would think to include has already been @'ed. I'll keep an eye out for anyone seeming to be interested in galls.

This is wonderful! So many people are excited about gall week!
I was going over all the comments. Do you think next year we should try to do it earlier? I do think that for California this is good timing, but I'd love to get more people in. I guess we'll try it this year, and then decide what to do next.
@gyrrlfalcon - I love the new idea! "The Galls Next Door" will make an awesome t-shirt (and buttons).
Here's the project link again -

發佈由 merav 約 2 年 前

@anudibranchmom - I think for now, we mostly need to spread the word. I saw that there are countless gall projects, for different states and cities. If you'd like, you can tag their leaders here or message them?
We could also create a list of resources people could use to get started in gall hunting, maybe by region? We could do that as a journal post in the project itself, unless there's a better idea.

發佈由 merav 約 2 年 前

Looks fun - thanks for tagging me @giusy87! Is this project for galls specifically for galls observed this week or for any galls being uploaded this week? I have a whole bunch of gall pictures from months ago sitting on my phone that I have yet to upload - specifically lots of non-cynipini (eriophyidae?) galls which I'm not very good at identifying...

發佈由 oliverc29 約 2 年 前

@oliverc29 - this project is intended for observations that were observed during gall week. Older photos would be great for different projects, such as the North American projects tagged in our project description

發佈由 merav 約 2 年 前

Will do.

How are you defining "the first week of October"? Are you starting on October 1? 2? 4?

發佈由 srall 約 2 年 前

The banner on the top of the project states that it will be from 10/2 to 10/10 @srall

發佈由 kemper 約 2 年 前

Make sure you send a reminder at the start of the week to remind me, I am easily distracted by other wildlife :-)

發佈由 a_emmerson 約 2 年 前

@merav, what do you mean by "regular" vs "old-fashioned" projects?
And BTW, last weekend I found a bunch of round green galls on a small oak, only took one white-light photo but they looked kind of powder blue under UV.

發佈由 moonlittrails 約 2 年 前

A regular/ new project will accumulate observations automatically, depending on the parameters set. For a BioBlitz, for example, it's easy - you set the polygon and the date, and it will do the rest. Same with "Ants of Santa Clara County". But for gall week, it wouldn't work, as we would need to define every possible gall-inducing organism, which won't be possible, as we'd like to get not only the Cynipid gall wasps and gall midges, but also the unknowns, observations of structures where we don't know who induced the gall. And I'd be happy to see the photos of your galls!

發佈由 merav 約 2 年 前

Hopefully,I will be able to add something to this lovely project. October means dark evenings here, no iNatting during weekdays and slim chance of clement weather during the weekend. And most of leaves are fallen by then. But good luck to everybody in the more southern areas.

發佈由 jurga_li 約 2 年 前

Is there anyone in the community who might be willing to come and do a short presentation to my two Girl Scout troops about this? Or meet us out at a park? We are based in San Jose. We are doing the Citizen Science journey, and this would fit right in with that. We are hoping to have our first meeting on the weekend of Oct 2-3. Many thanks for anyone who can point us in the right direction. --- Trisha Bergthold -

發佈由 trishabergthold 大約 2 年 前

@trishabergthold I don't know how old your scouts are, but one thing to keep in mind is that no one under 13 can have their own iNat account without their parent or guardian making them an account via

發佈由 tiwane 大約 2 年 前

@tiwane , thank you. I have girls ranging from 1st through 11th grade between the two troops. We can definitely work it so that the youngers are either with one of their parents or one of the older girls. The discovery and photography are the exciting parts for them. I don't think they care so much about having their name attached to their finds.

發佈由 trishabergthold 大約 2 年 前

I tried to resist, but if everyone's going to be throwing their best puns out there... How about a nod to public radio:
"Gall Things Considered"
Especially since many of us (myself included) end up with photos where we're like, "Wait, is this thing a gall or not?!"

發佈由 harsiparker 大約 2 年 前

I like that one. "Gall Things Considered" is cool! Especially since I've found a couple mysteries this week when looking for actual galls. And mistakenly identified some galls wrong, in a big way. Oops. Still learning, but having fun.

發佈由 beartracker 大約 2 年 前

I love Gall Things Considered! I'm (g)all in!

I went on a gall walk today and found tons of them!

Here are the comments that were posted on the Galls of California page before people were encouraged to join the discussion here instead:

Great idea! I'm in. And I will be thinking about the t-shirt design!--kdff about 2 months ago

Is this only for the Bay Area?--biocowboy about 2 months ago

If it is statewide, I'm sure there are a number of us in Southern California who will participate. Unfortunately I will be in Arizona most of that week, but if I'm in California on any of the days, I'll go gall hunting. Millie --milliebasden about 2 months ago

I know @milliebasden is always up for a good gall hunt. Awesome work!
