Gall Mite Set I

My research points me to the *Eriophyes* (https://w.wiki/GcAD) genus, but I don't have a good guess for the species 🤷‍♂️

Here are the galls of the Cynips quercusfolii, better known as Cherry gall wasp (in Dutch: Eikengalwesp). The small cup-shaped galls are from the Neuroterus albipes, also known as the Snooth spangle gall wasp (in Dutch: Plaatjesgalwesp)

The galls contain the female larvae. Mostly to be found underneath oak leaves.

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
