Miridae - Closterocoris amoenus
Residence near Rosebowl, Pasadena, Los Angeles County, California, USA

So far I've found only a couple of these, in a mallow in my garden (Sphaeralcea sulphurea). Immature certainly looks like an ant mimic, more so off camera.
Based on mesonotal wing pads overlapping the metanotal pad, this should be a fifth-instar nymph.
I don't know what the adults look like, though I might have some candidates. For now, I'm trying to raise what I can find into adult stage for better ID.
Any preliminary suggestions based on knowledge of nymphal stages? Antennal segment two is rather long, and this nymph has a rather distinct looking dorsal spine probably retained as an adult.
