Platymeris rhadamanthus, the red spot assassin bug, is a species of true bugs belonging to the family Reduviidae. [1]
Platymeris rhadamanthus can reach a length of 3.8–4 centimetres (1.5–1.6 in). The basic color of the body is black, with orange or red spots on the hemelytra. The legs are covered with short hair, and femurs are crossed by a red band. Both the orange-spot and red-spot color forms have the same morphological characters including the morphology of male and female genitalia. [2] This venomous nocturnal predator has needle-like mouth parts designed for sucking juices out other insects. It has a painful sting, comparable to that of a hornet. It feeds on small invertebrates, but mainly on the rhinoceros beetles. [3]
Historically, the orange colour form has also been known as P. mombo, however it is now known to be a colour form rather than a species.
This species can be found in Angola, Burundi, Democratic Republic of the Congo, Gabon, Kenya, Malawi, Mozambique, Republic of South Africa, Tanzania, Zambia and Zanzibar. [1] It prefers open areas with small participation of tree vegetation. [2]
Harmonia axyridis, most commonly known as the harlequin, multicolored Asian, or Asian ladybeetle, is a large coccinellid beetle. This is one of the most variable species in the world, with an exceptionally wide range of color forms. It is native to eastern Asia, but has been artificially introduced to North America and Europe to control aphids and scale insects. It is now common, well known, and spreading in those regions, and has also established in Africa and widely across South America. This species is conspicuous in North America, where it may locally be known as the Halloween ladybeetle. It earns this name as it often invades homes during October to overwinter.
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.
The wheel bug is a species of large assassin bug in the family Reduviidae. The species is one of the largest terrestrial true bugs in North America, reaching up to 1.5 inches (38 mm) in length in their adult stage. They are sexually dimorphic, in that males are somewhat smaller than the females. A characteristic structure is the wheel-shaped pronotal armor. Wheel bugs prey on caterpillars and beetles, such as Japanese beetles, the cabbage worm, orange dogs, tent caterpillars, and the Mexican bean beetle, all of which they pierce with their beak to inject salivary fluids that dissolve soft tissue. Wheel bugs are most active in daylight, though they may engage in predatory behaviors at night in areas illuminated by lights. Because most of their prey are pests, wheel bugs are considered beneficial.
Dynastinae or rhinoceros beetles are a subfamily of the scarab beetle family (Scarabaeidae). Other common names – some for particular groups of rhinoceros beetles – include Hercules beetles, unicorn beetles or horn beetles. Over 1500 species and 225 genera of rhinoceros beetles are known.
Reduvius personatus or the masked hunter is an insect belonging to the assassin bug (Reduviidae) family. The name is because its nymphs camouflage themselves with dust. The masked hunter is a predator of small arthropods, including woodlice, lacewings, earwigs, bed bugs and termites. Masked hunters do not feed on human blood, but can bite humans in self-defense when mishandled. The bite can be extremely painful, but masked hunters do not carry Chagas disease.
The Emesinae, or thread-legged bugs, are a subfamily of the Reduviidae. They are conspicuously different from the other reduviids by their very slender body form. They are stalking, predatory insects that can be collected on palm fronds, cliffs, spider webbing, or near lights at night. They walk on their mid and hind legs; the front pair is raptorial. Some groups specialize on spiders. Very little is known about emesines except that many species are found in the tropics. Pedro Wygodzinsky wrote the most recent revision of this group.
Insect toxins are various protein toxins produced by insect species.
Coccinellidae is a widespread family of small beetles ranging in size from 0.8 to 18 mm. The family is commonly known as ladybugs in North America and ladybirds in Britain and other parts of the English-speaking world. Entomologists prefer the names ladybird beetles or lady beetles as these insects are not classified as true bugs.
Platymeris is a genus of assassin bug (Reduviidae). Platymeris species are often used in laboratories and as pets. The venom of this genus has been studied in a laboratory setting.
Metarhizium majus is the name given to a group of fungal isolates that are known to be virulent against Scarabaeidae, a family of beetles. Previously, this species has had variety status in Metarhizium anisopliae and its name is derived from characteristically very large spores for the genus Metarhizium. There has been considerable interest in developing isolates of this species into mycoinsecticides: especially for coconut and oil palm beetle pests in SE Asia, the Pacific region and Africa.
Acanthaspis petax is a species of assassin bug that preys primarily on ants, but also on a variety of small insects, such as flies, small grasshoppers and beetles. The nymphs of this species create a pile of ant carcasses on their backs for camouflage. The adults do not use camouflage and are coloured with a red and black pattern.
Platymeris laevicollis is a venomous predatory true bug from central Africa that can be found in forests, scrublands, grasslands, and croplands. They are efficient predators and are used by farmers on coconut plantations to control herbivorous pests such as the rhinoceros beetle. As a true bug of the order Hemiptera, it has needle-like mouth parts designed for sucking juices out of plants or other insects instead of chewing. P. laevicollis has sharp stylets in its proboscis or rostrum used to pierce the exoskeleton of its prey. Saliva is then injected into the prey which liquifies its tissues,and the rostrum is then used to suck out the digested fluids. If disturbed, it is capable of a defensive bite considered to be more painful than a bee sting.
The mammoth wasp is a very large wasp, with the female reaching up to 6 centimetres (2.4 in), whereas the male is smaller. The species can be seen in warm weather, from May to September.
The Asiatic rhinoceros beetle, coconut rhinoceros beetle or coconut palm rhinoceros beetle, is a species of rhinoceros beetle of the family Scarabaeidae. O. rhinoceros attacks the developing fronds of raffia, coconut, oil, and other palms in tropical Asia and a number of Pacific islands. Damaged fronds show typical triangular cuts. The beetle kills the palms when the growing point is destroyed during feeding.
Ptilocnemus lemur is a species of feather-legged bug in the family Reduviidae native to Australia. Commonly known as the feather-legged assassin bug, it is a predator with a specialized gland called a trichome that it uses to attract and paralyse ants before feeding on them.
Psytalla horrida is an insect in the assassin bug genus Psytalla. It is commonly called the horrid king assassin bug or giant spiny assassin bug.
Chelymorpha cassidea, known generally as the Argus tortoise beetle or milkweed tortoise beetle, is a species of leaf beetle in the family Chrysomelidae. It is found in the Caribbean and North America.
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.
Acanthaspis quinquespinosa is a species of assassin bug found in India, Sri Lanka, Myanmar, Nepal and Tibet. It is a predator, and both nymphs and adults feed on termites, beetles, caterpillars and other insect prey.
