    Some plants have tiny droplets of clear sticky liquid, others have brown sticky stuff.

    Any idea what problem it may be? Scales?

    Where is it? Around the peristome? If the clear sticky liquid is dripping and oozzing down the front of the pitcher from the peristome it is nectar. This is normal I have it happen all the time. But brown liquid? I don't know what that is and it doesn't sound good to me.

    Many Nepenthes also produce nectar on the leaves, tendril and outside of the pitcher. They could be anywhere from clear to brown color as it dries. My khasiana makes brown blobs of goo on the ground from nectar dripping off the peristome also...

    I suspect this is what your seeing as opposed to sugar droplets caused by sucking insects.

    Tony, the droplets are all under the leaves, hardly on the pitchers. It only started about a month ago. I've checked for sucking insects but found none so far.

    Btw, the droplets are more on younger leaves and what sucking insects would cause such droplets?

    Could it be just moisture condensation?

    Well your right about scale usually being on the underside of the leaf, but the scale themselves are not normally sticky. What you find is that the upper side of the leaf just below the infested leaf will be come coated with sugar secretion. In humid environments this sugar will become coated in mildew. Scale also tend to be along the midvein of the leaf and the edges. Soft scale can also be easily wiped off the leaf with a moist papertowel. I don't think it is scale or any other insect.

    I got worried because more and more of my plants are producing the droplets. The highlanders are worse, there are dents where the droplets form...like someone has been pricking them with a needle!

    I suspected scale because I had some on my sarracenias before.

    Speaking of dents or "pimples" on the Nepenthes leaves. Tony I sometimes get these on newly developed leaves what is it? The feel just like a brail (for blind people" sign. Anyways ever had or seen it?
