Idolomantis is a monotypic genus of praying mantises in the family Empusidae. It contains the single species, Idolomantis diabolica, commonly known as the devil's flower mantis or giant devil's flower mantis. It is one of the largest species of praying mantises, and is possibly the largest that mimics flowers. [3]
Idolomantis diabolica is a large mantis of the family Empusidae. Females grow to be about 13 cm (5.1 in) in length and males to about 10 cm (3.9 in). [4] It is native to Ethiopia, Kenya, Malawi, Somalia, Tanzania, South Sudan, and Uganda. Its threat display is magnificently colored, with red, white, blue, purple, and black. [5]
The basic anatomical structure of I. diabolica is similar to most species of the order Mantodea, but the morphology of each species varies according to its native habitat, and this species is modified somewhat to enhance its floral mimicry.
The head of I. diabolica contains three vital components: compound eyes, antennae, and mandibles. The compound eyes, composed of thousands of individual photoreceptor cells, enable good eyesight. The arrangement of photoreceptor units, for instance, allows the insect to capture a perceptual span of 180°. [6] This allows I. diabolica to identify prey and predators without increasing its vulnerability by spoiling its camouflage. The antennae, a pair of long and thin bristles, serve as the insect's sensory perception. Projecting outwards, the antennae can detect much in the surrounding environment such as chemicals, movement, and odors. The male antennae are more developed than those of the females and are feather-like. This allows them to track down females by detecting the pheromones released by the females. These pheromones notify the males that the females are ready to reproduce. [7] The mandibles can be used to "tear, puncture, or grind" food. [8]
The thorax constitutes a large portion of the insect's body. As in all insects, it is composed of three segments: the prothorax, mesothorax, and metathorax. [7] Each section "contains one pair of legs, however, the wings are found only on the mesothoracic and metathoracic segments." [7]
Reproductive organs, respiratory organs, and other organ systems occupy the abdominal region of the insect.
When confronted by a predator, I. diabolica initiates a deimatic display in an attempt "to scare off or momentarily distract a predator". [9] Its front legs, specifically the femora, are raised to expose the conspicuous patterns depicted on the bottom of the thorax and abdomen. Similarly, the wings display a combination of vibrant colours. Observational analysis of I. diabolica in captive settings revealed an additional tactic of shifting its wings left to right to startle and confuse predators. [10]
In the presence of prey, I. diabolica, impersonating a flower, remains motionless. Its objective is to seduce the insect into its striking zone. In this zone, Idolomantis diabolica uses the tibiae of its legs to grasp and maintain a strong grip on the prey. The mandibles are then "wielded as formidable weapons" to decapitate and devour the prey. [8] The dietary preference of I. diabolica is exclusively airborne insects, specifically flies, moths, butterflies and beetles. [11]
Before reproducing, mature females display dimorphic features in an attempt to attract males. Females lower the tips of their abdomens and raise their wings slightly to expose more of the uppermost side of the abdomen, thus releasing pheromone to attract a mate. [11] However, sexual cannibalism is prominent among pairs of I. diabolica that remain in captivity. Due to their precautious nature, intrusive environments lead to aggressive behaviour. For example, a female, in the process of copulating, adopts predatorial instincts, which often conclude with the female devouring the head of the male. [6]
A female deposits some 10 to 50 eggs in an ootheca. [11] The period between egg-laying and hatching varies according to temperature and humidity, but about fifty days would be typical. [12] After hatching, the nymphs feed on small insects such as houseflies and fruit flies. Males develop into adults after undergoing ecdysis about seven times into successive instars, while females mature after about eight instars. [11] The lifespan of I. diabolica varies according to the habitat, but is typically about 12 months. [6]
Due to its beauty and dramatic displays, I. diabolica is considered a prestigious pet. Consumers, specifically in the Western Hemisphere, purchase thousands on a yearly basis.[ citation needed ]
The Carolina mantis is a species of praying mantis of the subfamily Stagmomantinae.
The European mantis is a large hemimetabolic insect in the family of the Mantidae ('mantids'), which is the largest family of the order Mantodea (mantises). Their common name praying mantis is derived from the distinctive posture of the first pair of legs that can be observed in animals in repose. It resembles a praying attitude. Both males and females have elongated bodies with two pairs of wings. The most striking features that all Mantodea share are a very mobile, triangular head with large compound eyes and their first pair of legs, which is highly modified for the efficient capture and restraint of fast-moving or flying prey.
Empusidae is a family of plant-mimicking mantises, consisting of 10 genera, in two subfamilies. Unlike many other mantis families, the Empusidae are a monophyletic lineage. Empusidae mantises are ambush predators, with mouthparts adapted to feeding on other insects and small animals. The majority of Empusidae species are distributed throughout Africa, but they are also found in Southeast Asia and in the southern parts of Europe.
Antheraea polyphemus, the Polyphemus moth, is a North American member of the family Saturniidae, the giant silk moths. It is a tan-colored moth, with an average wingspan of 15 cm (6 in). The most notable feature of the moth is its large, purplish eyespots on its two hindwings. The eyespots give it its name – from the Greek myth of the cyclops Polyphemus. The species was first described by Pieter Cramer in 1776. The species is widespread in continental North America, with local populations found throughout subarctic Canada and the United States. The caterpillar can eat 86,000 times its weight at emergence in a little less than two months. Polyphemus moths are considered to be very polyphagous, meaning they eat from a wide variety of plants.
Hymenopus coronatus is a mantis from the tropical forests of Southeast Asia. It is known by various common names, including walking flower mantis, orchid-blossom mantid and (pink) orchid mantis. It is one of several species known as flower mantids, a reference to their unique physical form and behaviour, which often involves moving with a “swaying” motion, as if being “blown” in the breeze. Several species have evolved to mimic orchid flowers as a hunting and camouflaging strategy, “hiding” themselves in plain view and preying upon pollinating insects that visit the blooms. They are known to grab their prey with blinding speed.
Ant mimicry or myrmecomorphy is mimicry of ants by other organisms; it has evolved over 70 times. Ants are abundant all over the world, and potential predators that rely on vision to identify their prey, such as birds and wasps, normally avoid them, because they are either unpalatable or aggressive. Some arthropods mimic ants to escape predation, while some predators of ants, especially spiders, mimic them anatomically and behaviourally in aggressive mimicry. Ant mimicry has existed almost as long as ants themselves; the earliest ant mimics in the fossil record appear in the mid Cretaceous alongside the earliest ants.
Flower mantises are praying mantises that use a special form of camouflage referred to as aggressive mimicry, which they not only use to attract prey, but avoid predators as well. These insects have specific colorations and behaviors that mimic flowers in their surrounding habitats.
Phyllocrania paradoxa, common name ghost mantis, is a small species of mantis from Africa remarkable for its leaf-like body. It is one of the three species in the genus Phyllocrania. It is known for its distinct and exclusive camouflaged appearance of a dry weathered leaf.
Litaneutria minor, or the agile ground mantis or minor ground mantid, is native to the drier regions of North America. L. minor is found in the United States in Colorado, Arizona to Mexico, and the eastern regions of Washington to California. They also can be found in Canada in the southern Okanagan Valley and are Canada's only native mantis. They are very active hunters and will be seen running across the ground from early spring to late summer.
Metallyticus splendidus is a rare species of praying mantis found in Southeast Asia. It has an iridescent appearance.
Pseudoharpax virescens, common name Gambian spotted-eye flower mantis, is a species of praying mantis native to western, central and eastern Africa. It takes its name from two eye spots on the dorsal side of the abdomen of adult females.
Empusa pennata, or the conehead mantis, is a species of praying mantis in genus Empusa native to the Mediterranean Region. It can be found in Portugal, Spain, southern France, Italy and on the mediterranean coasts of Morocco, Algeria, Tunisia, Libya and Egypt. Because of its cryptic nature, or also possibly because of its fragmented, low-density populations, it is rarely encountered in the wild.
Orthodera novaezealandiae, known as the New Zealand mantis or the New Zealand praying mantis, is a species of praying mantis which is, as both the scientific name and common names suggest, indigenous and endemic to New Zealand.
Empusa fasciata is a species of praying mantis in the genus Empusa in the order Mantodea.
Pseudocreobotra wahlbergi, or the spiny flower mantis, is a small flower mantis native to southern and eastern Africa.
Tarachodes afzelii, commonly known as the Tanzanian ground mantis, is a species of praying mantis in the family Eremiaphilidae. It is native to woodland in Western and Central Africa.
The external morphology of Lepidoptera is the physiological structure of the bodies of insects belonging to the order Lepidoptera, also known as butterflies and moths. Lepidoptera are distinguished from other orders by the presence of scales on the external parts of the body and appendages, especially the wings. Butterflies and moths vary in size from microlepidoptera only a few millimetres long, to a wingspan of many inches such as the Atlas moth. Comprising over 160,000 described species, the Lepidoptera possess variations of the basic body structure which has evolved to gain advantages in adaptation and distribution.
Mantises are an order (Mantodea) of insects that contains over 2,400 species in about 460 genera in 33 families. The largest family is the Mantidae ("mantids"). Mantises are distributed worldwide in temperate and tropical habitats. They have triangular heads with bulging eyes supported on flexible necks. Their elongated bodies may or may not have wings, but all Mantodea have forelegs that are greatly enlarged and adapted for catching and gripping prey; their upright posture, while remaining stationary with forearms folded, has led to the common name praying mantis.
Pseudocreobotra ocellata, known as the African flower mantis or with other species as the spiny flower mantis, is a flower mantis native to Africa, ranging from Angola and South Africa in the south to Uganda in the east and Senegal in the west. It was described by the French naturalist Palisot de Beauvois in 1805.
Climaciella brunnea, known sometimes by the common names wasp mantidfly, western mantidfly, and brown mantidfly, is a predatory neuropteran insect in the family Mantispidae.
