Feeding on Hydrophyllum appendiculatum (the Great Waterleaf) growing in my urban native plant garden.
A. arabis? White clypeus, but I haven't seen this species before so I'd appreciate a second opinion. Unsure about facial proportions, and when I put it through DiscoverLife it eliminated arabis when I selected 'absent or obscure pitting' for the scutum, which is what it appears to be here (in any case the scutum and terga appear heavily tessellated). Also, it kind of looks like there's a tiny bit of white on the paraocular areas next to the clypeus on either side, so not sure what that's about. Average-sized, not small like a male ziziae or such. On Cardamine.
