Remarks

• Structure: Female scale black, very elongate and slender, exuviae at the anterior extremity, the second exuvia broader than the scale itself. A very thick ventral scale is formed, this of the same color and texture as the dorsal scale and the two so closely fused that the adult insect is enclosed as within a flattened tube. Male scale similar to that of the female, but short (Ferris, 1941d).
• Biology: Occurring on the under side of the leaves (Ferris, 1941d). Found developing beneath the trichomes and epidermis of Tillandsia. (Malumphy, 2012)
• General Remarks: Description and illustration of adult female by Ferris (1941d) and by Miller et al. (1984). Description of first instar nymph by Miller et al. (1984).
