A mucous membrane or mucosa (plural, mucosae or mucosas; Latin tunica mucosa) is a lining of mostly endodermal origin.f the lining is torn or broken, mucus is incapable of performing its roles of preventing infection and retaining tissue moisture levels. In the female, the glans clitoridis and the clitoral hood have mucous membranes.
The cucumber you refer to as regular is the most common field-grown variety. Known as a slicing cucumber, it ranges in size from 6 to 9 inches, and its dark-green skin is usually waxed to prevent moisture loss. The English cucumber, which may be called seedless, European, burpless, or hothouse (which is where it is commercially grown), grows to between 1 and 2 feet in length. Slimmer and smooth-skinned, it is wrapped in plastic and can cost as much as $2 per cucumber.
The adult spotted cucumber beetle is approximately the same size as the striped, however it has a yellowish-green body with 12 black spots on its wing covers. Both beetles have black heads. The larvae of both beetles are between 1/3 to 3/4 in length and white to yellowish-white in color. The eggs are yellowish-orange in color. Despite these slight differences in appearance, both of these cucumber beetles are similar in their life cycles, the damage they do, and the methods used to control them.
