Sexual Dimorphism and Identification

Sexual dimorphism in African Twig Mantises becomes particularly evident in their physical characteristics. These features facilitate the identification of the male and female mantises:

Male Sexing

L5 and above: Males at the L5 stage and beyond are essentially thinner than females. They exhibit 3-4 small appendages on the upper side of the abdomen.
Adult: Adult males have fully developed wings and are capable of flight. They remain essentially thinner than females, with the base of their antennas thickened. Their wings are longer than their abdomen, providing them with the ability to engage in aerial movements.

Female Sexing

L5: Female mantises at the L5 stage appear more compact than their male counterparts. They possess 3-4 prominent, visible appendages on the upper side of the abdomen.
Adult: Adult females have reduced wings and are nonvolant, meaning they are unable to fly. They maintain a more compact body structure than males, and their antennas are relatively thin.

Enclosure Guidelines for African Twig Mantises

Creating an appropriate and comfortable enclosure for African Twig Mantises (Popa spurca) is essential to ensuring their well-being and optimal development. These remarkable insects require specific environmental conditions and habitat components to thrive. Here’s a comprehensive guide to setting up an ideal enclosure for these mantises:

Lighting and Photoperiod

African Twig Mantises require a suitable light source to mimic their natural day-night cycle. Daylight is generally sufficient, but the use of halogen lamps or similar artificial lighting is recommended to provide consistent illumination. Aim for a light cycle of approximately 12 hours of light and 12 hours of darkness to replicate their natural environment.

Temperature and Humidity

Maintaining the right temperature and humidity levels is crucial for the health of African Twig Mantises:

Daytime Temperature: Keep the daytime temperature within the range of 25°C to 30°C. This warmth promotes activity and growth.
Night Temperature: Ensure the nighttime temperature doesn’t drop below 20°C to prevent stress and discomfort.
Daytime Humidity: Maintain a humidity level between 50% and 60% during the day.
Night Humidity: Increase the humidity to a range of 60% to 70% at night to simulate the higher moisture levels often experienced during the night.
Humidity Maintenance: Regularly spray the enclosure every 2 to 3 days to maintain appropriate humidity levels and provide a suitable environment for molting and hydration.

Terrarium Dimensions and Setup

When setting up the enclosure, consider the following aspects:

Minimal Terrarium Dimensions for Single Keeping: For individual mantises, the enclosure should be at least 15cm x 15cm x 25cm to provide sufficient space for movement and exploration.
Minimal Terrarium Dimensions for Community Keeping: If keeping multiple mantis nymphs up to the L5 stage, a terrarium of around 20cm x 20cm x 30cm is recommended. However, community keeping is not recommended beyond the L5 stage due to the increasing aggressiveness of African Twig Mantises as they grow.
