An already structurally-frail organism, this insect was discovered in a very dry, desiccated stated, and therefore, was missing a number of its body parts, including its antennae. Arthropods possess an exoskeleton composed of chitin, which 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. However, under certain circumstances, as in this case, the exoskeleton will dry, thereby loosing its flexibility, becoming brittle and vulnerable to attack from environmental forces, leading to exoskeletal fractures of this normally resilient exterior. This chitinous exoskeleton gives rise to a myriad of morphologic shapes, including scales, setae, antennae, legs, and mouthparts.
