so a forum search for brevipalpus turned no results so hopefully this is helpful for others also in the future. if anyone can offer tips for wiping these guys out or confirm the ID it would be appreciated. they are not spider mites and I have already released phytoseiulus persimilis into the nursery with no effect. I have another general predatory mite on the way which may or may not help. once I've finished doing h2o2 flushes for fungus gnat larvae I can find out! aaargh pests are ruining my life! in a not depressing but comedic tragedy kind if way.
