Opisthopsis rufithorax, commonly known as the "strobe ant," is a fascinating species found primarily in Queensland, Australia. Known for their bright orange and black coloration, massive eyes, and unique strobe-like movement, these ants are a delight for ant enthusiasts.
Opisthopsis rufithorax
Opisthopsis rufithorax ants are characterized by their rapid, darting movements, making them appear as if they are flashing. They are predominantly found in open forests, dry sclerophyll forests, and eucalyptus forests. The name "rufithorax" refers to the red color of their thorax and part of their abdomen. Workers are rather timid and will quickly move to the opposite side of a tree trunk or drop to the ground when approached.
When purchasing an Opisthopsis rufithorax colony, you can expect to receive a queen and several workers. Given their specific care requirements and unique behaviors, they are ideal for both beginners and experienced ant keepers. Proper housing, temperature, humidity, and nutrition are crucial for maintaining a healthy colony.
Housing
Opisthopsis rufithorax can be housed in various setups, including test tubes and small nests once the colony exceeds 15 workers. Due to their climbing abilities, using fluon (PTFE) barriers is essential to prevent escapes. Colonies typically have less than a few hundred members and develop slowly, so it's important not to rush them into a large formicarium.
Temperature and Humidity
- Temperature: Maintain a feeding area temperature of 21-30°C and a nest temperature of 24-28°C. These ants thrive in warm conditions similar to their natural habitat.
- Humidity: Maintain a feeding area humidity level of 30-80% and a nest humidity level of 50-70%. Regular monitoring is necessary to provide a comfortable environment for the ants.
Feeding
Opisthopsis rufithorax has a specific diet:
- Proteins: Diptera such as flies and mosquitoes.
- Carbohydrates: Raw honey or Sunburst ant nectar. They tend to reject most processed sugars, so natural options are better received. Queens do not require feeding until workers arrive. Once workers are present, regular feeding of sugars and proteins is essential.
Hibernation
These ants do not require hibernation, making their care relatively straightforward throughout the year.
Observing Opisthopsis rufithorax is a rewarding experience due to their unique strobe-like movement and large eyes. These ants rely heavily on their vision and will follow movements, making feeding particularly engaging. Despite their strobe behavior outside the nest, they move normally within the nest to conserve energy.
