Mexican creeper, native cotton, oleander, pikake, plumeria, poinciana, red pepper, sweet potato, ti and wisteria. The first sign of hibiscus snow scale is the presence of armor on upper and lower leaf surfaces, fruits, and stems of plants. The adult female armor is flat, irregularly oyster sheIl or pear-shaped, tough, white or dirty white.
Males are long and narrow with three ridges running lengthwise.
The armor must be pried off to reveal the insect. Females and feeding nymphs are attached to the plant by hair-like mouthparts. The female body is a flat, elongated oval shape without wings, legs, or eyes, Dead ones are dark brown and are dried rather than plump. Since scales are spread by introduction of infested material and are difficult to identify to species outside of the lab, scales of the genus Pinnaspis are a quarantine problem on exported potted plants, cut flowers, and cut foliage. EGGS Eggs are laid under the armor of the female where they develop and hatch.
