    It's a section of Masdevallia I like a lot.
    Never had any viruses on Masdevallia. Do you see it on the leaf or flowers or both?

    I like this section too. Bean Yellow Mosaic Virus is the one that is most often seen in Pleurothallids. It shows up only on the new leaves and then fades as they age. If you hold up the new leaf to the light, the virus shows up as a mosaic pattern of darker and lighter greens. There are others that will infect them, but BYMV is easily spread not only by tools, but also by aphids.

    Oh, ok! So that's what I had on my Masdevallia and Dracula orchids when they have a been visited by aphids this year. It didn't spread to other parts of the plant and new leaves once I got rid of the aphids thou. The plants look ok now, except for the infected leaves.

    This is an infected leaf from Dracula gorgona. What should I do? Plant still flowers like it's ok.

    Hi Gerrit,

    That could just be physical damage from the aphids. Watch for patterns on the new growth…easy to see on Dracula. I have had to throw away some plants in the past.

    I agree with Chuck. That isn't virus. I would guess it is insect damage.

    Thanks Chuck and Marni. Very reassuring to hear that this is not a virus. The aphids problem was in spring, so if there was a virus involved, it would have already spread I guess.

    Check when you have new growths coming out on this plant to see that the leaves are a nice solid green.
