Terrarium Setup and Requirements

Terrarium Size for Single and Community Keeping

  1. For single keeping of Acromantis formosana, a terrarium size of at least 10cm x 10cm x 15cm is recommended. This provides sufficient space for the mantis to move around comfortably and molt safely.
  2. If you plan to keep multiple mantids in a community setup, opt for a larger terrarium with dimensions of around 30cm x 30cm x 50cm. This size accommodates approximately four pairs of Acromantis formosana, allowing them to coexist without feeling crowded.

Essential Decorations and Substrate for a Natural Environment

  1. Acromantis formosana thrives in an environment that resembles its natural habitat. Decorate the terrarium with branches, plants, twigs, leaf litter, and bark sticks. These elements provide hiding spots, climbing opportunities, and enrich the mantis’s surroundings.
  2. Use an earth-sand-mixture or pulp as the substrate, simulating the ground texture of the mantis’s native environment. The substrate also aids in maintaining appropriate humidity levels.

Recommended Light Source, Length, and Temperature

  1. Acromantis formosana usually do well with natural daylight, but you can enhance their well-being with supplemental lighting. Halogen lamps or other appropriate light sources can provide the necessary illumination.
  2. Aim for a light length of approximately 12 hours per day to mimic the natural day-night cycle. Consistent lighting helps regulate the mantis’s behavior and maintains their biological rhythm.
  3. Maintaining a daytime temperature between 25°C to 30°C is crucial for the mantis’s health and activity. Make sure the terrarium offers temperature gradients, allowing the mantis to move to warmer or cooler areas as needed.

Ideal Humidity Levels and Spraying Tips

  1. Acromantis formosana prefers a daytime humidity level of 50% to 70%. During the night, increase the humidity to 60% to 80%. These levels imitate the humid environments where these mantids thrive.
  2. Regularly spraying the terrarium in the evenings helps maintain the desired humidity. However, be cautious not to make the enclosure too wet, as excess moisture can be detrimental to the mantis’s health.

By carefully designing the terrarium setup to reflect the natural habitat of Acromantis formosana, you create an enriching environment that promotes their well-being, ensuring a captivating and rewarding experience as you observe these unique mantids in their element.

Feeding and Nutrition

Preferred Food Sources

Acromantis formosana, like many other mantis species, is a voracious predator. Their diet primarily consists of live insects. Offer a variety of appropriately sized prey items to meet their nutritional needs and encourage natural hunting behavior. Preferred food sources include:

  1. Drosophila (fruit flies)
  2. Flies
  3. Moths
  4. Cockroaches
  5. Small crickets

Importance of a Balanced Diet to Ensure Proper Growth and Health

Providing a balanced diet is crucial for the proper growth, development, and overall health of Acromantis formosana. A diverse diet ensures that they receive essential nutrients, vitamins, and minerals necessary for their well-being.

A varied and nutritious diet also contributes to:

  1. Healthy Development: Adequate nutrition supports proper molting, ensuring the mantis can shed its skin successfully as it grows.
  2. Longevity: A well-fed mantis is more likely to lead a longer and healthier life, bringing joy to its keeper for an extended period.
  3. Reproductive Success: Proper nutrition is essential for females to produce healthy oothecae (egg cases) and for males to maintain vitality during mating.
  4. Behavioral Fulfillment: Offering a diverse diet allows Acromantis formosana to engage in natural hunting behaviors, promoting mental and physical stimulation.

Ensure the prey items are of appropriate size, as mantids may struggle with overly large or aggressive prey. Additionally, feeding should be consistent and sufficient, considering the mantis’s size and activity level. A well-fed and contented Acromantis formosana will flourish under your care, rewarding you with a fascinating display of predatory prowess and natural beauty.

Sexing and Lifespan

Techniques for Sexing Nymphs and Adult Mantids

  1. Nymphs: Until L3 (third instar stage), sexing Acromantis formosana nymphs can be challenging. At this stage, they often display ant-mimicry, making it difficult to determine their gender. However, once they reach L5 (fifth instar stage) and above, sexing becomes possible. Counting the abdominal segments at the bottom of the abdomen is the reliable method for identifying their sex. Females typically have 8 segments, while males have fewer.
  2. Adult Mantids: Sexing adult Acromantis formosana mantids involves observing specific physical characteristics. In females, the under wings are generally longer than the upper wings. For males, the upper wings are longer than the under wings. Additionally, females tend to have a slightly larger and more robust abdomen compared to males.

Average Lifespan of Male and Female Acromantis formosana

The lifespan of Acromantis formosana can vary slightly based on environmental conditions and overall care. On average, the lifespan for both male and female mantids is approximately 6 to 9 months. However, females may live slightly longer than males.

Reproduction and Breeding

Understanding Copulation Readiness and Behavior

Before attempting to breed Acromantis formosana, it’s essential to ensure that both male and female mantids are sexually mature. Typically, they reach maturity at the adult stage (after undergoing several molts). Signs of copulation readiness include:

  • Males: Males become more active and alert, actively seeking a mate. They may also display courtship behaviors, such as wing flapping and posturing.
  • Females: Females emit pheromones to signal their readiness for mating. They may also adopt a receptive posture, allowing the male to mount their back during copulation.

Ootheca Building, Description, and Care

After successful copulation, the female will proceed to lay oothecae, which are protective egg cases. Oothecae serve as a safe haven for the developing eggs. The process of ootheca building involves the following steps:

  1. Ootheca Description: Acromantis formosana oothecae are box-shaped and longish, measuring approximately 18mm in length. They have a brown coloration.
  2. Ootheca Care: Once the female lays the ootheca, it is crucial to ensure it remains undisturbed. Provide a secure and sheltered area within the terrarium for the female to deposit the ootheca. Avoid handling or moving the ootheca, as this can damage the delicate eggs inside.

Incubation Period and Hatching Process

The incubation period of Acromantis formosana oothecae can vary depending on temperature and humidity conditions. On average, it takes approximately 4 to 8 weeks for the eggs to hatch.

During this period, it is essential to maintain a stable and suitable environment to ensure successful hatching. Keep the temperature within the range of 22°C to 28°C and the humidity levels between 50% to 80%. Avoid excessive fluctuations in these parameters, as they may negatively impact the developing eggs.

Once the incubation period is complete, tiny nymphs, measuring approximately 6mm, will emerge from the ootheca. These young mantids will exhibit black coloration and ant-mimicry, similar to earlier nymph stages.
