The praying water fly is a unique and mysterious aquatic insect in nature, which attracts attention for its unusually striking appearance and superb predation skills.
Living near a variety of waters, from streams to lakes to swamps, these insects have long been intriguing entomologists, ecologists and evolutionary biologists.
The scientific name of the praying mantis derives from the fact that their forelimbs are similar to praying mantises, but they are not related to praying mantises, but belong to the mantis family. Although mantis water flies are not the most well-known population in the insect kingdom, they play a unique and important role in nature.
«——[Taxonomy·] ——»
1. External morphological features
The external morphological characteristics of mantis water flies are one of the primary bases for their taxonomic identification, and their body structure is unique in the insect kingdom, with a series of striking characteristics.
Mantis water flies usually have a green or brown color, which helps them hide in vegetation near the waters. Its body length varies between species, ranging from a few millimeters to several centimeters.
The forelimbs of the praying water fly are similar to those of the praying mantis, hence the name "praying mantis mode". These forelimbs have a strong grip and are used to catch prey.
The forewings of the praying mantis fly are usually spread out in a transparent or pale color, contrasting with the color of its body, giving it a unique appearance. These forewings also often have spots or striae , and the differences between species make them easier to classify and identify.
2. Classification status
The taxonomic status of mantis water flies has been an important topic in entomological research, and they belong to the family Praying mantises, which also includes a number of other special insects. Species in the family Nymphalidae share some common features in both morphology and life history, such as the shape of forelimbs and predatory habits.
3. Diversity of species
The diversity of mantis water fly species is amazing, it is estimated that there are about 300 species of praying water flies currently known, and more new species are constantly being discovered. These species are distributed all over the world, from temperate to tropical, from mountains to plains, and are almost ubiquitous.
This widespread distribution makes mantis water flies an interesting object to study, as they may play different roles in different ecosystems. Different species of mantis water flies differ in external morphology, behavior, life history and ecological niche.
«——[Ecology.]——»
1. Ecological role
Mantis water flies play an important ecological role in aquatic ecosystems, especially in preying on insects and maintaining ecological balance. They are considered beneficial predators and often prey on the larvae of some pests such as aphids and mosquitoes. This predatory behavior helps control the growth of pest populations and maintain the ecological balance of farmland and wetlands.
The praying water fly itself is also prey for other predators, including birds and spiders. This role in the food chain allows for complex ecological relationships between mantis water flies and other organisms that are essential for the stability of aquatic ecosystems.
2. Habitat selection
The diversity of habitat choices of praying water flies can be found near different types of waters, including streams, lakes, ponds, rivers and marshes, making studying the habitat preferences of praying water flies one of the keys to ecological research.
Habitat selection is related to the life history and food resources of mantis water flies, with some praying fly species preferring to select slow-moving water bodies because prey in these water bodies is easier to catch, while others are adapted to live in larger waters such as lakes, where prey species are more abundant.
3. Food sources
The food source of the praying water fly is mainly the larvae of other insects and aquatic insects, which live as their main lifestyle and use their specialized forelimbs to capture prey. Different species of praying water flies may prey on different species of prey, depending on their chosen habitat and environment.
At the larval stage, mantis water flies are also predatory. They often choose to look for prey in the water, such as larvae of aquatic insects and other small aquatic organisms, and the predation behavior of mantis water fly larvae has an important impact on the food web and ecological balance of aquatic ecosystems.
«——[.Behavior.]——»
1. Predatory behavior
Timing of predation: Mantis water flies usually hunt during the day, especially in the morning light and dusk. They take advantage of the low light, making it easier to access their prey without being detected. This pattern of behavior coincides with the activity pattern of its predatory target, providing favorable conditions for predation success.
Targets of predation: Mantis water flies prey mainly on other insects, including aphids, mosquitoes and other small flying insects. Different species of praying water flies may choose different types of prey, depending on their habitat and environment. Some species are more inclined to prey on aquatic insects, while others prey more on terrestrial insects.
Predation strategy: The predation strategy of praying water flies can be divided into two main types: waiting and camouflage, in which they will quietly crouch in plant leaves or other hidden positions, wait for prey to approach, and then quickly attack.
In camouflaged predation, some mantis water fly species mimic other insects, such as mosquitoes, to trick their prey and then prey unexpectedly.
2. The process of food capture
Predation skills: The forelimbs of praying water flies are great for catching prey. They have a strong grip that makes it almost impossible for their prey to escape.
When preying, mantis water flies use their forelimbs to hold their prey tightly and then use their blade-like jaws to gnaw at it. This predation technique requires a high degree of coordination and precision, and is the key to successful hunting in mantis water flies.
Physiological basis of predatory behavior: The predatory behavior of praying water flies involves neurological, muscular and biochemical processes, and researchers have tried to reveal the physiological basis of predation behavior through anatomical and physiological studies, including the function of sensory organs, the regulation of the nervous system, and the coordination of muscle movement.
3. Reproductive behavior
Mating behavior: The mating behavior of praying water flies usually involves complex courtship displays, male water mantis water flies may display a variety of behaviors, such as dancing, making sounds, releasing pheromones, etc., to attract females, and females usually choose the most attractive male to mate.
Spawning patterns: Mantis water flies lay their eggs differently from species to species, with some species laying their eggs on the surface of the water to allow the eggs to hatch in the water, while others may lay their eggs on plant leaves or other hidden places.
Growth and development of larvae: The larval stage of mantis water flies usually occurs in water, and they go through a series of growth and development stages until they become adults. The growth and development of larvae is closely related to environmental conditions, including water quality, temperature, and food resources.
«——[.Reproduction.]——»
1. Mating behavior
Courtship display: The mating behavior of praying mantis flies usually involves complex courtship displays, and male mantis water flies will display a variety of behaviors to attract females. These behaviors include rocking, dancing, making sounds, and releasing pheromones. The purpose of courtship displays is to attract females and get them to identify themselves as mating partners.
Female selection: Female mantis water flies usually select the most attractive males for mating, this female selectivity helps maintain good genetic quality and optimize the chances of survival of offspring, researchers gain insight into female preference for male traits by observing female selection behavior.
Male and female mating behavior: The mating behavior of mantis water flies usually occurs on plants near the habitat, males usually fly near the female for courtship display, if accepted by the female, mating behavior occurs, and the mating behavior of praying water flies is usually a short and rapid process.
2. Spawning method
How the eggs are laid by the mantis: The eggs of the praying water fly are usually laid in the environment, and their way of laying eggs varies from species to species. Some species lay their eggs on the surface of the water, where the eggs hatch, while others may lay their eggs on plant leaves or other hidden places, and the way they lay eggs is closely related to the species' ecological environment and life history strategy.
Number of eggs: Mantis water flies also lay different numbers of eggs from species to species, with some species laying only a small number of eggs at a time, while others may lay a large number of eggs, and this difference may be influenced by food resources, life history strategies, and environmental conditions.
Egg protection: Some mantis waterfly species take steps to protect the eggs to increase larval survival. This includes the way the eggs are attached to the plant, as well as the creation of a protective filamentous substance around the eggs, which is essential for the survival of the larvae.
3. Development of the egg
Incubation process: The eggs of praying mantis water flies hatch in the environment, the incubation process is affected by environmental conditions such as temperature and humidity, and the eggs release larvae after hatching.
Larval development: The larvae of the praying water fly go through multiple stages of development and usually live in water. The development of larvae is closely related to food resources and environmental conditions, and larvae prey on larvae or small aquatic organisms of other aquatic insects.
Larvae to adults: The larvae eventually turn into adults after a series of molts. This process involves the growth and morphological changes of larvae to adapt to aerial life.
«——[·Evolution.]——»
1. System classification
Taxonomic History: The taxonomic history of mantis water flies is full of twists and turns, they were once classified as a class of dragonflies, but later molecular systematics studies revealed that they were different from dragonflies and were therefore reclassified as mantis or neuromantis, a taxonomic shift that reflects the continuous development and evolution of evolutionary research.
Taxonomic relationship: The praying water fly is a member of the order Neuromantis, which is related to insects such as mosquitoes, dragonflies and praying mantises. Through molecular systematic, morphological and genetic studies, researchers have continued to refine the status and kinship of mantis water flies in the taxonomic system.
2. Evolutionary history
