Sphodromantis lineola, common name African mantis or African praying mantis, is a species of praying mantis from Africa sometimes raised in captivity. [1] [2] [3] [4] S. lineola is often colored green, however they can also be colored different types of brown. The brown colored individuals have also been observed with purple colored eyes. [5] It may be distinguished from S. baccettii by the absence of blue-black spots on its forearms. [6]

Visual System

The visual system of the S. lineola is the most studied aspect of this species. In fact, this species is the most studied in this topic. Since S. lineola are sit and wait predators they have a well developed motion detection visual system. This species of mantis like most other species have apposition based compound eyes and mantises are the only invertebrates known to use stereoscopic vision. They use looming signals in order to detect and calculate other organisms or objects heading towards them using motion-in-depth perception. Using this system they are able to calculate based on speed whether to resort to predatory or defensive strikes. They also have also demonstrated to respond to visual cues which are not of their usual prey or that they have ever encountered which complements their larger range of prey due to scarcity in nature. However some studies do denote that there is no evidence of this species being able to judge the size of their prey and mostly just focus on their depth, which can probably be connected to their generalist predatory behavior. [7] [8] [9] [10] [11]

Predation

Much Like the rest of the mantids they are mainly insectivores preying on other insects. However, Mantids are also known to be able to capture and feed on vertebrates. These ferocious predators are not picky predators and are very opportunistic. This is due to the fact that in nature prey is scarce and are often in a state of hunger. Hence, why female mantids including this species will resort to post mating cannibalism to supplement the energy and nutrition needed to survive and reproduce. [12] Like most praying mantis this species is an ambush predator. They use their well developed motion detection visual systems as well as proprioceptive information to detect prey and then deliver a carefully calculated and extremely accurate strike. [13] [14]

Reproduction

Mate Attraction

Males are mainly attracted to females through olfactory and visual signals as well as with tactile cues. Studies have shown that hormones alone are not responsible for attraction of males by females. Females must perform mainly specific antennal movements as a premating behavior along with hormones in order to attract the attention of the males. [15]

Sexual Cannibalism

Many mantid species are known to show cannibalism post copulation, S. lineola being one of this species. [16] Studies have come to the conclusion that this behavior can be attributed female mantids needing nutrition in order to produce more offspring. It has been documented that females of this species are commonly in a state of hunger in natural settings which is shown to be a driver of this behavior. In captivity, under circumstances in which females are well fed, they have shown to not perform cannibalism on the male mantid after copulation. Other ways for males to avoid being eaten by their mate is through different courtship behaviors such as sneaking on the female or swiftly jumping on their back whilst trying to avoid being eaten. Although under most natural circumstances these are often ineffective. [16]

Scientific Relevance

S. lineola is being used for many different studies most of which involving its visual system. Their ability to be kept in captivity has allowed them to become a very used species in this field. They have contributed in the field for theories and topics like the flicker effect idea; the effect of invisible noise on insect motion detection; motion-in-depth perception of mantises; reaction to different stimuli; the physiology of the mantis eye and many other studies based around their vision. They are considered to be the most studied species of mantis in this field. [7] [8] [9] [10] [11] [13] [17] Similarly, this has also led to the study of the mechanisms of mantis predatory behaviors and responses to prey. Furthermore, this species has also been used to study the sexual cannibalism behavior seen so often in mantids as well as helping identify the first putative pheromone in a praying mantid. [15]

<span class="mw-page-title-main">European mantis</span> Species of praying mantis

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.

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. 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. Spiders are the most common ant mimics. Additionally, some arthropods mimic ants to escape predation, while others mimic ants anatomically and behaviourally to hunt ants 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. Indeed one of the earliest, Burmomyrma, was initially classified as an ant.

Sexual cannibalism is when an animal, usually the female, cannibalizes its mate prior to, during, or after copulation. It is a trait observed in many arachnid orders and several insect and crustacean clades. Several hypotheses to explain this seemingly paradoxical behavior have been proposed. The adaptive foraging hypothesis, aggressive spillover hypothesis and mistaken identity hypothesis are among the proposed hypotheses to explain how sexual cannibalism evolved. This behavior is believed to have evolved as a manifestation of sexual conflict, occurring when the reproductive interests of males and females differ. In many species that exhibit sexual cannibalism, the female consumes the male upon detection. Females of cannibalistic species are generally hostile and unwilling to mate; thus many males of these species have developed adaptive behaviors to counteract female aggression.

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.
