Cattleya with crepey (crepe paper like) texture on leaves

[cattmad]

Without a photo it is difficult to make a true assessment but from your comments that it is also affecting other plants it suggests to me from your description that they are under watered and are suffering stress from lack of moisture.
I would be confident to suggest it is not an infestation problem and if the pseudo bulbs are not withering from root problems (such as over watering causing root rot)your concern may be easily overcome by the application of more water. Hope this helps.
