Rhynocoris tristis is a species of assassin bug family (Reduviidae), in the subfamily Harpactorinae. R. tristis is a polyphagous predator found in sub-Saharan Africa. [1]
R. tristis is associated with Stylosanthes guinaensis , and this association is thought to be due to the prey species attracted by flowers of S. guinaensis. [2] R. tristis is unusual in the insect world in that males provide paternal care by guarding egg masses [3] from parasitic wasps and insect predators. [1] Males will also cannibalize some of the eggs that they guard. [4] R. tristis prefers to lay its eggs on the stems of plants, in contrast to most members of the harpactorinae, which prefer to lay them on the undersides of leaves. [1]
Hemiptera is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, bed bugs, and shield bugs. They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera. Many insects commonly known as "bugs", especially in American English, belong to other orders; for example, the lovebug is a fly and the May bug and ladybug are beetles.
The Reduviidae are a large cosmopolitan family of the order Hemiptera. Among the Hemiptera and together with the Nabidae almost all species are terrestrial ambush predators: most other predatory Hemiptera are aquatic. The main examples of nonpredatory Reduviidae are some blood-sucking ectoparasites in the subfamily Triatominae. Though spectacular exceptions are known, most members of the family are fairly easily recognizable; they have a relatively narrow neck, sturdy build, and formidable curved proboscis. Large specimens should be handled with caution, if at all, because they sometimes defend themselves with a very painful stab from the proboscis.
Coreidae is a large family of predominantly sap-suckling insects in the Hemipteran suborder Heteroptera. The name "Coreidae" derives from the genus Coreus, which derives from the Ancient Greek κόρις (kóris) meaning bedbug.
The Cimicomorpha are an infraorder of insects in the order Hemiptera, the true bugs. The rostrum and other morphology of all members apparently is adapted to feeding on animals as their prey or hosts. Members include bed bugs, bat bugs, assassin bugs, and pirate bugs.
Sociality is the degree to which individuals in an animal population tend to associate in social groups (gregariousness) and form cooperative societies.
The scissortail sergeant or striptailed damselfish is a large damselfish. It earns its name from the black-striped tail and sides, which are reminiscent of the insignia of a military Sergeant, being similar to those of the sergeant major damselfish. It grows to a length of about 16 centimetres (6.3 in).
Parental care is a behavioural and evolutionary strategy adopted by some animals, involving a parental investment being made to the evolutionary fitness of offspring. Patterns of parental care are widespread and highly diverse across the animal kingdom. There is great variation in different animal groups in terms of how parents care for offspring, and the amount of resources invested by parents. For example, there may be considerable variation in the amount of care invested by each sex, where females may invest more in some species, males invest more in others, or investment may be shared equally. Numerous hypotheses have been proposed to describe this variation and patterns in parental care that exist between the sexes, as well as among species.
Pisulus tipuliformis is a species of assassin bug in the subfamily Harpactorinae. The females of this species exhibit maternal care, and can distinguish their own eggs from other females of the same species.
Rhynocoris albopilosus is a species of assassin bug in the Harpactorinae subfamily. This species, which is found in West Africa, exhibits a degree of male parental care, with males standing watch over females' eggs.
Pahabengkakia piliceps is a species of true bug (harpactorinae) found in Thailand. This species is apparently a specialist predator of the stingless bee Trigona collina. Larval P. piliceps mimic the bees, and eggs are laid in the bees' hives. Nymphs of P. piliceps were found to occupy the nest entrance and kill returning foraging bees. The assassin bug does not seem to predate other Trigona species, even though they are also present in the area.
Rhynocoris is a genus of assassin bug, family (Reduviidae), in the subfamily Harpactorinae. Species are recorded from Asia, mainland Europe, Africa and North America.
Zelus longipes is an assassin bug (Reduviidae) that is a member of the harpactorinae subfamily. Its distribution ranges include southern North America, Central America, and South America, especially in agroecosystems in Brazil.
Zelus renardii, the leaf hopper assassin bug, is a predacious insect contained within tribe Harpactorini. Diurnal and found on both wild and crop plants, Z. renardii has spread from its native habitats in western North and Central America into three other biogeographic regions across the globe.
Sphedanolestes cingulatus is a species of assassin bug belonging to the family Reduviidae, in the subfamily Harpactorinae.
Rhynocoris iracundus is an assassin and thread-legged bug belonging to the family Reduviidae, subfamily Harpactorinae. The species was first described by Nikolaus Poda von Neuhaus in 1761.
Belostoma flumineum is a North American species of giant water bug. They are a common predator in ponds and wetlands. They are relatively large, reaching 2–2.5 cm (0.79–0.98 in) in length. As with other species of the Belostomatidae family, the fathers take care of the offspring. Exclusive paternal care has been the focus of many studies done on this species. Other studies have been done on food webs and predation pressure using this species because they are an apex predator in their preferred habitats.
Rhynocoris longifrons is a species of assassin bug in the family Reduviidae. It is a predator of other insects and is found in Asia. Crops on which it is found feeding on pests include pigeon pea, cardamom and peanuts. The insects are potentially useful in biological control because they are more resistant to pesticides than are the pests they consume.
Rhynocoris marginatus is a species of assassin bug in the family Reduviidae. It is a predator of other insects and is found in Asia. Crops in India on which it has been found feeding on pests include sugarcane, pigeon pea, cardamom, cotton, tea, and peanuts. The insects are potentially useful in biological control because they are more resistant to pesticides than are the pests on which they feed.
Cydnocoris is a genus of assassin bugs found in tropical Asia. It has been suggested that this genus be either treated as a synonym of CutocorisStål, 1859 or the later name be suppressed.
Rihirbus is a genus of assassin bug from the tropical parts of the Oriental region. They belong to the Harpactorinae and the genus is unique in having the fore tibiae with incurved tips and the apex having a long tooth. They show sexual dimorphism and are polymorphic making their identification to species complicated. Females are larger and wider. R. trochantericus takes about 49 days to develop from egg to adult in southern India.
