On California buckeye
Found by @suburbanpoison
Gall on Deerweed.
Galls on Symphoricarpos albus. Various similar galls were visible on nearby S. albus plants.
Plant: San Jacinto Beardtongue (Penstemon clevelandii connatus). @tchester @nancyasquith @cwbarrows @susanmf This is the first time I’ve ever seen this. It reminds me of Contarinia on Epilobium. Your thoughts, please!
