| Title: | Microscopic bedbug scanning electron micrograph. |
| Description: | This scanning electron micrograph (SEM) revealed some of the ultrastructural morphology displayed on the dorsal exoskeletal surface of the head region of a bedbug, Cimex lectularius. A member of the phylum Arthropoda, this insect has three pairs of jointed legs, hence the name, 'Arthro' = jointed, and 'poda' = legs. What appeared to be 'hair' was not hair at all, but sensory structures known as 'setae', and are composed of chitin, the same material as the rest of this organism's exoskeleton. Chitin is a molecule made up of bound units of acetylglucosamine, joined in such a way as to allow for increased points at which hydrogen bonding can occur. In this way chitin provides increased strength, and durability as an exoskeletal foundation. |
