All galls were harvested by Dr. Melanie Body, except for the blueberry galls and wasps that were harvested by Dr. Patrick Edger, and the first Phylloxera galls that were harvested by Dr. Dan Chitwood.
Galls were scanned by Dr. Michelle Quigley and Dr. Dan Chitwood.

Phylloxera is a relative of aphid that forms galls on grapevines. These are galls on the leaves of Vitis riparia, the river grape.
I’m hoping to see eggs in the galls by X ray CT, but already spotted an insect flying around. Hope this “bug” doesn’t affect the reconstruction! 😂 pic.twitter.com/7slu5KyLx0

These tiny wasps (𝘏𝘦𝘮𝘢𝘥𝘢𝘴 𝘯𝘶𝘣𝘪𝘭𝘪𝘱𝘦𝘯𝘯𝘪𝘴) induce stem galls in blueberries (𝘝𝘢𝘤𝘤𝘪𝘯𝘪𝘶𝘮), where their larvae develop. Looking forward to perfecting the perfect high res scan of these–and time series of gall development–with @ProteinUniverse! pic.twitter.com/sFokxODUeJ

Wasps induce stem galls in blueberry. The long, callose wound results from successive punctures, depositing eggs to the opposite side. In cross-section, nascent gall chambers can be seen, pushing the vasculature out of the way.

A relative of the grape tube gall maker, Schizomyia vitiscoryloides, makes grape blister galls. These galls are round and purple, but within them is a long horned-shaped chamber that houses the larvae (which can be seen). (3/5) pic.twitter.com/0NFSu46tKs

Phylloxera, an aphid relative, destroys the roots of wine grapes but forms galls in leaves as well, shown here.
Other insects produce a fantastic variety of gall shapes in grapevine, see below!

Great CT scan by @EndlessForms of #cynipid #oak #gall. Wasp in center chamber. A lot like one from Miocene! What plant genes does the insect manipulate to get this morphology? See insect, legs, eyes, in second scan. Beautiful! Live photo: @MelanieJABody pic.twitter.com/xmydrvKl3b

Lastly, this gall still has the developing insect inside. pic.twitter.com/qci47IeFUf

The insects in this gall have mostly left leaving their tunnels behind. pic.twitter.com/4m1VIuSP3m

Xray CT scan of hedgehog gall, Acraspis erinacei. Very very cool! https://t.co/GGLlO70HcW pic.twitter.com/fHO0pmipki

More galls from @MelanieJABody and @jackcschultz. This is several an Oak Spangle Galls on an oak leaf. pic.twitter.com/gOTkNajqMh

Starting the year with another gall from @MelanieJABody and @jackcschultz . This is a Wooly Gall on an oak leaf. pic.twitter.com/B6nzOfH5CR

This is a Witch Hazel Cone Gall on an oak leaf. You can see the veins that the insect used to "steal" nutrients from the plant. The exit hole of the insect can be see on the bottom. @MelanieJABody @jackcschultz pic.twitter.com/rKt5cuYoAG

This is an Jumping Gall on Oak. The detail on the gall's surface is wonderful and you can see the insect inside. @MelanieJABody @jackcschultz pic.twitter.com/SL9Q91nrNt

Two months ago, I posted an oak leaf covered with these galls. Today, we have a closer look at a Spangle gall. @MelanieJABody and @jackcschultz pic.twitter.com/bErPRabiNp
