#galls — Public Fediverse posts

Some galls are really wild. This one is from Cedar-Hawthorn Rust, a fungal disease that alternates between cedar and hawthorn hosts.

This is it on Black Hawthorn, looking like tiny growths of Spanish Moss emerging from the leaf

Happen to walk past an Oak Tree a few days ago that was just loaded with Hedgehog Galls. I usually have to look it over carefully to spot any. This year there are multiple Galls on most every if not all leaves😮

The inside pics were taken years ago and weren't all that well focused...

Some Biorhiza Pallida are messing with my oak saplings!

Well. Time flies.. Anyway. Over a year later the #oak #galls dried nicely so the little Hobbit and I started the #ink making process.

First the ingredients. We're using a simple recipe and I base it on using 10 grams of galls.

1 - 4 grams of Iron(II) sulfate
2 - 4 grams of Gum arabic
3 - 30ml of water (from our well, boiled, no chemicals)
4 - 10grams of oak gall

Ripe and ready to eat :)

These colorful lesions were originally thought to be just fungal infections (Botryosphaeria dothidea) but were eventually found to harbor midge larvae (Asteromyia carbonifera) that farm the fungi for food and use the hardened hyphae to prevent (sometimes) parasitic wasps from ovipositing into the gall. In turn, emerging female flies dutifully transmit spores to new plants each generation. #goldenrod #fly #diptera #fungus #fungi #mutualism #gall #galls #solidago #cecidomyiidae #insects #entomology

Here are the stats for Gall Week 2025: 13,300 observations, 1004 species, and 886 participants. These numbers will climb as people upload their pics and manually add them to the project. #GallWeek2025 #gall #galls #inaturalist #insects #mites #nature https://www.inaturalist.org/projects/gall-week-september-2025

One thing you learn very quickly when photographing oak galls is that bald-faced hornets are huge gall fans, too. #GallWeek2025 #gall #galls #cynipidae #oaks #nectar #wasps #insects #biology #hymentopera #hornets

14/09/2025 - A sunny day out. Slow stroll looking at trees and bugs. Aberdeenshire was looking lovely today in the September sunshine. Two new things I've not come across before, both on the same oak tree, oak artichoke galls and a little larch ladybird.

Found some banded bullet galls (Kokkocynips imbricariae) yesterday. I also found a dollar near the tree. It was a good day. Media, PA, USA. #GallWeek2025 #gall #galls #wasps #cynipidae #insects #entomology #oaks #quercus

Excellent podcast on galls featuring Adam Kranz. #GallWeek2025 #gall #galls #insects #mites #biology https://naturesarchive.com/2023/04/10/spring-galls/

I don't wear earrings but it seems like there should be more shops selling ones that look like oak galls. Or *are* oak galls. #earrings #art #jewelry #cynipidae #galls #insects

If you'd like to learn more about the cherry gall azure here's the 2005 paper by Pavulaan and Wright that describes it. #lepidoptera #galls #prunus #butterflies #lycaenidae #entomology #insects https://leplog.wordpress.com/wp-content/uploads/2014/04/pavulaan-wright-2005-c-serotina.pdf

If you have a black cherry loaded with spindle-shaped leaf galls, keep your eyes peeled for the omnivorous caterpillar that feeds on them, the cherry gall azure (Celastrina serotina). #lepidoptera #galls #prunus #butterflies #lycaenidae #entomology #insects https://www.inaturalist.org/observations/82888035

Black cherry leaf gall (Eriophyes cerasicrumena) that has split open and released the vermiform mites that have spent the summer inside. #GallWeek2025 #gall #galls #mites #cherry #prunus #biology #eriophyidae #macrophotography

These oak button galls (Neuroterus umbilicatus) give a nice sense of how small cynipid wasps are. I've seen photographs that are so loaded them that you can barely see the leaf surface. #GallWeek2025 #gall #galls #cynipidae #oaks #quercus #entomology #nature #wasps

Jewel oak gall (Acraspis quercushirta), living up to its name. Little Crum Creek Park, Swarthmore, PA, USA. #GallWeek2025 #gall #galls #cynipidae #oaks #quercus #entomology #nature #wasp

Yesterday's fun gall find was Phylloteras sigma (Cynipidae), a rarely-photographed beauty with no common name. iNaturalist observations are mainly in PA, DE, MD, VA, and DC but BugGuide lists NY, too. Reported on both Quercus alba and Q. muehlenbergii. Little Crum Creek Park, Swarthmore, PA. #GallWeek2025 #gall #galls #cynipidae #oaks #quercus #entomology #nature #gallformers

took the fancy camera to high park this morning!

i was mostly looking for galls for #GallWeek but i also saw plenty of sand wasps enjoying the sun, and a coyote! i was walking away from it but it crossed the street to avoid me anyway and a car that was going too fast had to stop for it 🙄

(there are Plans to gradually #BanCars in High Park, people are big mad)

Stumbled onto this gem while admiring observations in iNaturalist's Gall Week 2025 project. The two-tailed gumtree gall (Apiomorpha duplex) is, per "Brisbane Insects and Spiders" blog, the world's largest gall. Like many galls made by scale insects in the Eriococcidae, the species makes sexually-dimorphic galls. This gall is induced by a female; male galls are knobs on leaves and don't seem to be photographed much. #GallWeek2025 #eucalyptus #gall #galls #homoptera #insect #gumtree #entomology #inaturalist #australia

@colinpurrington Wow, they are amazing! Found some nice galls here too :) #GallWeek2025 #galls #gall
