@ang spotted this insane insect.
On bridge handrail below redwood dominated ravine. Dead, faded color
Found this pair mating on chaparral current. Haven't quite done all my homework yet, but I don't think that's a known host for any of them.
From Fraxinus dipetala.
Common on ash (Fraxinus dipetala). Got to be this species but the host does not seem to be known.
