Ant mimicry in beetles
Adaptive advantage
rove beetle adaptive advantage
- structural ie; abdomen, legs, antenna to look like army ants
- behaviour; mimic, copy movement of ants etc
- chemical; producing odour similar to army ant
- therefore -> increases survival and reproduction of rove beetles.
Convergent evolution
- rove beetle displayed convergent evolution
- Convergent evolution is the independent evolution of similar features in species through a period of time.
-rove beetles evolved : legs, antenna grew longer, slimmer abdomen to resemble army ants.
Predation
left: army ant
right: rove beetle
- rove beetles are predators to the army ant , the ants are a food source to the beetles.
- Therefore, increasing the chances of survival and reproduction of the beetles.
- decreasing the survival and reproduction chances of the army ant population.
- rove beetles maximises food resource inside the ant colony.
Rove beetle
Interspecific relationship
- interspecific interaction (predation)
- beetles mimic appearance, behaviour of ants
- enter colony -> prey on young ants
