Very little research has been done on classifying and identifying carbohydrates within insect adhesive secretions. So far, glucose , trehalose and mucopolysaccharides that contain glucose, galactose , mannose , beta- glucopyranose , and/or (N-acetyl-beta-) glucosamine have been identified as components of insect adhesives.
