How do you recognize hemispherical scale?

Adult scales are round and spherical of shape and shiny brown colored. Underneath the scale cover an adult female produces many eggs. Young crawlers hatch from these eggs and move throughout the plant. The young stages are oval, flat and almost translucent yellow. Hemispherical scales are usually found sitting in a row along the vein on the underside of the leaf. The size of the adult scales depends on the host plant.
