What is the difference between Batesian mimicry and Mullerian mimicry?
The main difference between Batesian and Mullerian mimicry is that Batesian mimicry is the exhibition of the characteristics of a dangerous species by a harmless species to avoid predators whereas Mullerian mimicry is the exhibition of similar characteristics by similar species to avoid predators.
What is the difference between mimicry and aggressive mimicry?
Aggressive mimicry is opposite in principle to defensive mimicry, where the mimic generally benefits from being treated as harmful. The mimic may resemble its own prey, or some other organism which is beneficial or at least not harmful to the prey.
What are the 4 types of mimicry?
THE ARTS OF DECEPTION: MIMICRY AND CAMOUFLAGE
- MIMICRY. There are three forms of mimicry utilized by both predator and prey: Batesian mimicry, Muellerian mimicry, and self-mimicry.
- Batesian Mimicry.
- Muellerian Mimicry.
- Self Mimicry.

What is an example of Batesian mimicry?
Both the harmless milk snake and the deadly coral snake mimic the warning signs of the moderately venomous false coral snake. The harmless milk snake mimicking the moderately venomous false coral snake is another example of batesian mimicry (a tasty treat dressed up as a venomous one).
What is meant by aggressive camouflage?
aggressive mimicry, a form of similarity in which a predator or parasite gains an advantage by its resemblance to a third party. This model may be the prey (or host) species itself, or it may be a species that the prey does not regard as threatening.
What is meant by Mullerian mimicry?
Müllerian mimicry, a form of biological resemblance in which two or more unrelated noxious, or dangerous, organisms exhibit closely similar warning systems, such as the same pattern of bright colours.
What are two types of mimicry?
The first distinction divides mimicry into two broad categories: ‘signal mimicry’ and ‘cue mimicry’. ‘Signal mimicry’ occurs when mimic and model share the same receiver, and ‘cue mimicry’ when mimic and model have different receivers or when there is no receiver for the model’s trait.
How do fireflies use mimicry?
Since Photuris females prey on males of other firefly species by mimicking their females’ flashes, the Photuris males may be using their mimicry to locate and seduce their own hunting females. This mimicry is without known parallel in other animal communicative systems.
What is the meaning of Müllerian mimicry?
Why is Batesian mimicry parasitic?
True Batesian mimicry is parasitic in nature with the model deriving no benefit and possible harm (Devries 1987). The mimics don’t share the models nasty taste or painful sting, just its appearance and behavior.
What does a firefly mimic?
What is aggressive mimicry in animals?
[ ə-grĕs′ĭv ] A form of mimicry in which a predator (the mimic) closely resembles another organism (the model) that is attractive to a third organism (the dupe) on which the mimic preys.
What is insect mimicry?
Insect Mimicry. Müllerian Mimicry. In Evolutionary Biology, mimicry occurs when one organ- ism copies the physical and/or behavioral traits of another organism in order to receive a selective advantage. Mullerian mimicry occurs when two or more harmful insect species have adapted to display like colors and patterns.
What insect mimics fireflies?
Photurius has earned the nickname ‘femme fatale lightening bug’ because she mimics the flash signals of the other fireflies in order to lure in unsuspecting males.
Why do female fireflies eat male fireflies?
Why? Because, as the saying goes, “You are what you eat.” In this case, the Photuris female eats the Photinus male to get chemical defences that are present in his blood. The toxins can be used to fight off predators like birds, spiders, ants and others.
What gene makes a firefly glow?
Firefly luciferase genes
The color of firefly bioluminescence is determined by the structure of luciferase. Firefly luciferase genes have been isolated from more than 30 species, producing light ranging in color from green to orange-yellow.
