WASMANNIAN MIMICRY Meaning and
Definition
-
Wasmannian mimicry is a term used in biology to describe a specific type of mimicry observed in certain species of social parasites. It is named after the Austrian entomologist Ferdinand Graf von Wasmann, who first described this phenomenon.
Wasmannian mimicry refers to a form of mimicry in which a social parasite imitates the appearance, behavior, or chemical signature of its host species in order to deceive and gain access to its resources or protection. This form of mimicry is commonly observed in ants and other social insects.
The mimics in this symbiotic relationship are often referred to as "inquilines" or "guest ants", while the host species are known as "host ants". The mimic species will typically infiltrate the host colony and blend in with the ants by adopting similar body shape, coloration, and/or behavioral patterns. They may also produce similar chemical signals to gain acceptance into the colony.
The purpose of Wasmannian mimicry is for the inquiline ants to exploit the host colony's resources such as food, shelter, or care provided by the host ants. By mimicking the hosts, the inquilines avoid detection and potential aggression from the host ants, allowing them to live undetected and benefit from the host colony's resources.
Wasmannian mimicry is a fascinating example of deception and adaptation in nature, illustrating the intricate strategies employed by social parasites for survival. It highlights the evolutionary arms race between parasites and hosts, with the mimics constantly evolving to better deceive the host species and the hosts developing countermeasures to detect and eliminate these intruders.
Etymology of WASMANNIAN MIMICRY
The term "Wasmannian mimicry" is derived from the name of a Belgian entomologist named Jean-Henri Fabre Wasmann (1859-1930), who extensively studied and documented a specific type of mimicry observed in ants.
Mimicry refers to the phenomenon where one species evolves to resemble another species in appearance, behavior, or other characteristics. In the case of Wasmannian mimicry, it specifically refers to a type of myrmecomorphy, which is mimicry of ants by other organisms.
Jean-Henri Fabre Wasmann extensively documented and researched this type of mimicry, particularly focusing on species of beetles and insects that have evolved to look like ants. His studies paved the way for understanding the various adaptive strategies and evolutionary processes behind mimicry in the natural world.
