Examination of intact biofilms growing on filters using a dissecting microscope (data not shown) revealed them to be uniform mats with a smooth, opalescent surface.
These needles will support large sheets of 20% opalescent fritted glass.
Hand specimens of fault material show quartz with grey to bluish colour and opalescent appearance.
This suffusion of body colour in the wings produces the opalescent effect which gave the mutation its name.
The thin, whitish, opalescent shell has a depressed turbinate shape.
The nails are opalescent and frequently are brittle and split at the free margin.
This is deposited as granules in its cytoplasm and is highly refractile and opalescent, making the organism look like a pearl.
Most mature males have opalescent and blackish wing bands.
