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

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

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

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

This is Andricus nigricens, another cynipid wasp that makes galls on oaks. Each lobe is home to a single larva (and possibly a parasite, because such is life). 2/5 #GallWeek2025 #gall #galls #wasps #oaks #cynipidae #inaturalist #quercus

Thread of the five types of galls I found yesterday. First up are oak rough bullet galls (Disholcaspis quercusmamma), protecting themselves from parasitic wasps by attracting ants with nectar.

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

Here's a screenshot of the 10 most common species found during a previous spring gall week on iNaturalist. Join the project linked above to learn more. #inaturalist #gall #galls #GallWasps #GallWeek2025 #gallformers #cynipidae

Found a wasp ovipositing into a Callirhytis furva gall on Saturday. Actual ID likely impossible (wasps are hard), but iNaturalist's computer vision guessed Periclistus, a cynipid genus that uses other cynipid galls as homes. But Periclistus is not, I think, a known inquiline of Callirhytis, so likely something else. #gall #galls #GallWeek #GallWeek2024 #wasp #hymenoptera #cynipidae #nature #macro #oak #inaturalist #insect
