The Fascinating Ant Universe: Discovering the Panda Ant
In the vibrant and intriguing world of insects, two fascinating creatures stand out - ants and velvet ants. Let's delve into their unique characteristics, defensive strategies, and surprising habits.
Ants, such as Camponotus ocreatus and Nomamyrmex esenbeckii, have followed hygiene and disinfection practices for millions of years. They use formic acid to maintain cleanliness, not only in their colonies but also in themselves. Interestingly, ants ingest formic acid through an acidopore on their rear ends. This acid is not only used for cleaning their own mouths and sponging structures, but also to disinfect sick larvae and their nests.
On the other hand, the Mutillidae family, commonly known as velvet ants, includes a species called Euspinolia militaris that resembles an ant but is actually a wasp. These insects are known for their bright and conspicuous color patterns, which serve as aposematic signals. Aposematism is a defensive mechanism used by organisms to reduce predation by advertising their capability to inflict pain or harm. The vibrant colors of velvet ants warn predators that they are powerful and can sting.
The Giant Tropical Ant, or Dinoponera australis, is another remarkable creature. This ant is one of the largest known ants and is found in abundance in tropical forests. Contrary to popular belief, the Giant Tropical Ant does not particularly like plants and prefers to feed on caterpillars and beetle larvae, making them top-level predators.

Velvet ants, like Euspinolia militaris, produce a sound by rubbing their body parts together, a behavior known as stridulation. Some species of ants can even absorb the color of a liquid they consume due to their transparent exoskeletons.
In an area of 10,000 square meters around Argentina's Iguazu Falls, there are 2.5 kilograms of ants, which is equal to the total biomass of all other types of rodents in the same area. This fascinating fact underscores the significant role ants play in our ecosystems.

Science reveals that ants, such as Camponotus ocreatus and Nomamyrmex esenbeckii, have executed hygiene and disinfection practices for millions of years. These practices include using formic acid to maintain cleanliness, a technique that extends to their own bodies and their colonies.
On the other hand, the Mutillidae family, or velvet ants, have a lifestyle that employs aposematic signals to deter predators, using their bright and conspicuous colors as a warning of their potential harm.
