Reproduction and Lifecycle

Sexual Dimorphism

In the Devil’s Flower Mantis, males and females exhibit sexual dimorphism. Males are generally smaller, have longer antennae, and thinner bodies than females. Here are the key differences:

  • Males: Smaller, longer antennae, thinner bodies
  • Females: Larger, shorter antennae, thicker bodies

Breeding and Oothecae

During breeding, the male mounts the female, and the process of transferring sperm begins. After mating, the female lays a protective case called an ootheca, which contains multiple eggs. Mothers do not survive long after laying the ootheca, but the case provides a durable shelter that enables the eggs to develop and endure winter.

Molting Process

As the Devil’s Flower Mantis ages, it undergoes a molting process to grow. Each life stage, or instar, is marked by a molt where the mantis sheds its old exoskeleton. The molting process can be a stressful experience, especially if the mantis is disturbed, but it is an essential part of the insect’s life cycle.

Sexual Cannibalism

Sexual cannibalism has been observed in the Devil’s Flower Mantis, where the female devours the male during or after mating. This behavior can provide the female with additional nutrients needed for successful reproduction.

Diet and Prey

Carnivorous Diet

The Devil’s Flower Mantis has a carnivorous diet, primarily feeding on live insects. Some common prey items include:

  • Crickets
  • Mealworms
  • Roaches

This mantis species often lies in wait on flowers, disguised as a flower itself, ready to snatch any unsuspecting prey that comes too close.

Feeding on Flying Insects

Another important prey group for the Devil’s Flower Mantis are flying insects. They are attracted to many types of flying insects, like:

  • Moths
  • Flies
  • Bees

Comparison between prey groups:

Crickets, Mealworms, Roaches Flying Insects (Moths, Flies, Bees)
Movement Crawling Flying
Attraction Lured through smell, color, and taste of Devil’s Flower Mantis Attracted to flowers and the mantis’ disguise

The Devil’s Flower Mantis has an incredible ability to adapt its hunting strategy based on the type of prey it encounters. By camouflaging itself as a flower, it can easily ambush flying and crawling insects alike.

Interaction with Humans

Is It Dangerous?

Devil’s Flower Mantis is not particularly dangerous to humans, as they are skittish insects that mainly use their front legs to catch prey. However, if threatened, they might engage in a deimatic display, which involves raising their thorax and displaying bright colors to scare off potential predators. This behavior is mostly harmless and does not pose a significant threat to humans.

Caring for a Captive Mantis

Caring for a captive Devil’s Flower Mantis requires attention to several factors. Here are the key aspects to consider:

  • Lifespan: They have a lifespan of around 12 months, shorter than many other praying mantises.
  • Environment: Mimic their natural habitat by providing sticks and foliage in their enclosure.
  • Temperature: Maintain a temperature of 75-85°F (24-29°C) during the day and slightly cooler at night.
  • Humidity: Keep humidity levels around 60-80% to promote healthy molting.

Some tips for caring for your captive mantis:

  • Keep them in a well-ventilated enclosure, such as a mesh cage, to ensure proper airflow.
  • Feed them small insects like flies or crickets, but be cautious not to overfeed them.
  • Regularly mist the enclosure to maintain humidity levels, but avoid creating a damp environment.
  • Provide horizontal perches for the mantis to hang onto during molting.

Pros and cons of keeping a Devil’s Flower Mantis as a pet:

Pros Cons
Strikingly beautiful Can be delicate to handle
Intriguing behavior Requires specific temperature and humidity conditions
Unique deimatic display Shorter lifespan compared to other mantises
Low aggression towards humans May be more challenging to care for than other insects

Environment and Enrichment

Creating a Naturalistic Environment

To create a naturalistic environment for a Devil’s Flower Mantis, consider the following:

  • Substrate: Use a combination of substrate like coco fiber, peat moss, or a mix of these.
  • Decoration and hiding spots: Add twigs and dried leaves for climbing and hiding.
  • Oothecae: Ensure proper space for attaching oothecae.
Element Requirement
Substrate Coco fiber, peat moss
Decorations Twigs, dried leaves
Space for oothecae Adequate

Providing Enrichment

Boosting the Devil’s Flower Mantis’ overall environment involves:

  • Heat: Use a heat lamp or heat mat to maintain the temperature around 27°C (80.6°F) during the day, dropping to 21°C (69.8°F) at night.
  • Cleaning: Replace substrate regularly and clean surfaces with paper towels to prevent mold, bacteria, and other unwanted invaders.
  • Feeding: Offer a diet with variety, such as flies, crickets, and moths, to add interest and mimic the natural hunting experience.
Feature Importance
Temperature control (Heat) Maintains a comfortable living environment
Cleaning Prevents the growth of mold and bacteria
Varied diet (Feeding) Enhances mental stimulation and nutrition

Remember, a well-maintained environment with enrichment will contribute to the overall health and happiness of your Devil’s Flower Mantis, allowing it to thrive throughout its lifespan. With these tips, you’ll create a captivating habitat that will keep both you and your mantis fascinated and engaged throughout its life.

Egyptian Flower Mantis

Hi Kevin,
A web search of “mantis Iraq” quickly produced a matching photo of an Egyptian Flower Mantis on the Arthropods of Iraq blog.  The species,
Blepharopsis mendica, is also known as the Devils Flower Mantis.  Upon searching our archives with the scientific name, we found this posting from 2010 of a nymph that we identified as having he common name Checkered Mantis.  We love both of your photos, and the threat posture is especially dramatic.

Dear Blewyn,
An insect’s common name frequently refers to a location, perhaps where it was first discovered or perhaps because it is common there, but insects have never respected international borders or walls.  Though your sighting was in Oman, we believe this is an Egyptian Flower Mantis,
Blepharopsis mendica.  Keeping Insects calls this a Thistle Mantis and states:  “This species of praying mantis is creamy-white to beige with light green stripes and light green ‘veins’ on the wings as adults. On its back this mantis has a small pointed shield under which the forearms are being kept. The inside of the front legs are orange and blue white white spots. These colors are shown in the threatening posture to deter predators. Blepharopsis mendica will grow to a size of about 5 to 6 cm, with little difference in size between the sexes. The males are more slender with wings that reach a little bit over the end of the abdomen. The females are bulkier with a wider prothorax and with wings that extend to just the end of the abdomen. The females have thin antennae while adult males have feathered antennae (antennae with large thick ‘hairs’ on it).”  The description of the antennae indicates this is a male. iNaturalist also uses the common name Egyptian Flower Mantis and also lists Oman as being in the range of the species.
