Beaked Twig Gall Wasps (Burnettweldia plumbella) form galls on several California oaks—including blue, leather, Muller’s, and scrub oaks. Adult wasps are tiny, just 3 to 4 mm long!
It's the first #WaspWednesday of 2025! Let's start the new year off with a gall wasp double-shot.
This lovely two-toned lady goes by Disholcaspis quercusmamma, or D.q. mamma for short. Upon becoming an adult in fall, she chews her way out of the gall she's lived in since spring. Being parthenogenic she has no need to mate in order to lay eggs that will be the spring sexual generation.
Sadly not all of her kind will make it to adulthood..see next post

It's GALL WEEK!!!
Here's a gall on a wild strawberry caused by a (likely undescribed) gall wasp species in the genus Diastrophus. The gall even started growing roots! Found in the boreal forest of northwestern Ontario, Canada.
Post your gall pics and join the project on iNaturalist. Get your gall on!!

Welcome to our 6th Gall Week event! Please add any new gall observations taken between September 7-15 to this project manually. Galls are structures induced by arthropods, fungi, and sometimes bacteria on plants. Please do not document here leaf miners or other evidence of feeding, unless they are gall-related. To participate, please join the project, document new observations between 9/7-15, and upload them manually to the project. Uploading observations can continue after the event ends as long as they were documented during that week. Don't forget to add information about the host plant - as a note, or even better, in the fields: Host and Host plant ID field. You can also link to the host plant observation, especially if you aren't sure what it was. Please do share your observations even if you are new to iNaturalist, and not sure yet how to use some of these features. If you're new to galling, you can check what are the best host plants in your area. You can use gall or insect b...
Well would you look at that - it's the gall of the Rose Root Gall Wasp (Diplolepis radicum). Despite their size and color these galls are hard to find given their position low on the stem and often covered by woodland detritus.
I've been on the look out for these for a few years now and, thanks to whoever mowed along the railroad tracks, a few galls were readily visible. Made a nice unexpected find.

Gall Week has started!! Get out there and find some galls, join the Gall Week April 2024 project in iNaturalist, and revel in these wonderful creations!
Here's some galls I found last year on an oak (a favorite host of many gall wasps).
