Hemiphileurus illatus is a species of rhinoceros beetle in the family Scarabaeidae. [1] [2] [3] Its range is the Southwestern United States. [4] Its common name is the lesser triceratops beetle.
As adults, this species is black with a pitted thorax and elytra. All six legs have short spines. They are 19 - 25 mm long. [5] They have not been observed to fly.
Both sexes have a pair of horns but the females' are much smaller, more like bumps or short nubs. Unlike their close cousins, Phileurus truncatus, neither sex has the notable third horn.
As larvae, they have cream-colored bodies and reddish-brown heads. They have a C-shaped posture, and move on their sides when above ground. [6]
As pupae, they are exarate with the ability to move their abdominal segments. As pupation progresses, their joints, faces, and tips of their legs change from tan to dark brown.
H. illatus is found in the Southwestern United States, primarily Arizona, Nevada, New Mexico, and California. It is found in urban and rural areas.
Adults are detritivores and scavengers. They eat fresh or rotting plant matter and other dead insects. In captivity, they will eat freshly-killed mealworms, fruits, and vegetables.They are protein feeders and show preference for insects and eggs over other food. [7]
Both adults and larvae burrow and spend most of their time underground. In captivity, they can be kept together or with other insect species relatively safely, but they may eat wounded or vulnerable individuals like eggs, larvae, or pupae. [7]
In urban areas, they may be found around compost heaps. Adults are attracted to UV light.
Adult beetles are capable of stridulation and produce a quiet but audible 'chirp' when agitated. [8]
They are not agricultural pests and pose no significant danger to humans or domestic animals.
It is legal to own and sell lesser triceratops beetles. Like many desert beetles, they are low-maintenance to keep, but are not especially popular or sought-after within the beetle-keeping community.
Lepidoptera is an order of insects that includes butterflies and moths. About 180,000 species of the Lepidoptera are described, in 126 families and 46 superfamilies, 10 percent of the total described species of living organisms. It is one of the most widespread and widely recognizable insect orders in the world. The Lepidoptera show many variations of the basic body structure that have evolved to gain advantages in lifestyle and distribution. Recent estimates suggest the order may have more species than earlier thought, and is among the four most species-rich orders, along with the Hymenoptera, Diptera, and Coleoptera.
Mealworms are the larval form of the yellow mealworm beetle, Tenebrio molitor, a species of darkling beetle. Like all holometabolic insects, they go through four life stages: egg, larva, pupa, and adult. Larvae typically measure about 2.5 centimetres (0.98 in) or more, whereas adults are generally 1.25 to 1.8 centimetres in length.
Manduca sexta is a moth of the family Sphingidae present through much of the Americas. The species was first described by Carl Linnaeus in his 1763 Centuria Insectorum.
Histeridae is a family of beetles commonly known as clown beetles or hister beetles. This very diverse group of beetles contains 3,900 species found worldwide. They can be easily identified by their shortened elytra that leaves two of the seven tergites exposed, and their geniculate (elbowed) antennae with clubbed ends. These predatory feeders are most active at night and will fake death if they feel threatened. This family of beetles will occupy almost any kind of niche throughout the world. Hister beetles have proved useful during forensic investigations to help in time of death estimation. Also, certain species are used in the control of livestock pests that infest dung and to control houseflies. Because they are predacious and will even eat other hister beetles, they must be isolated when collected.
Dermestidae are a family of Coleoptera that are commonly referred to as skin beetles. Other common names include larder beetle, hide or leather beetles, carpet beetles, and khapra beetles. There are over 1,800 species described.
The huhu beetle is a longhorn beetle endemic to New Zealand. It is the heaviest beetle found in New Zealand.
Holometabolism, also called complete metamorphosis, is a form of insect development which includes four life stages: egg, larva, pupa, and imago. Holometabolism is a synapomorphic trait of all insects in the superorder Endopterygota. Immature stages of holometabolous insects are very different from the mature stage. In some species the holometabolous life cycle prevents larvae from competing with adults because they inhabit different ecological niches. The morphology and behavior of each stage are adapted for different activities. For example, larval traits maximize feeding, growth, and development, while adult traits enable dispersal, mating, and egg laying. Some species of holometabolous insects protect and feed their offspring. Other insect developmental strategies include ametabolism and hemimetabolism.
The Hercules beetle is a species of rhinoceros beetle native to the rainforests of Central America, South America, and the Lesser Antilles. It is the longest extant species of beetle in the world, and is also one of the largest flying insects in the world.
Odontotaenius disjunctus, the patent-leather beetle or horned passalus, is a saproxylic beetle in the family Passalidae which can grow to just over an inch-and-a-half long, weigh 1-2 grams and are capable of pulling 50 times their own weight. They have been used to study several aspects of general family characteristics since the early 1900s but remain a relatively unknown species within the diverse Coleoptera order.
The Goliath beetles are any of the five species in the genus Goliathus. Goliath beetles are among the largest insects on Earth, if measured in terms of size, bulk and weight. They are members of subfamily Cetoniinae, within the family Scarabaeidae. Goliath beetles can be found in many of Africa's tropical forests, where they feed primarily on tree sap and fruit. Little appears to be known of the larval cycle in the wild, but in captivity, Goliathus beetles have been successfully reared from egg to adult using protein-rich foods such as commercial cat and dog food. Goliath beetles measure from 60–110 millimetres (2.4–4.3 in) for males and 50–80 millimetres (2.0–3.1 in) for females, as adults, and can reach weights of up to 80–100 grams (2.8–3.5 oz) in the larval stage, though the adults are only about half this weight. The females range from a dark chestnut brown to silky white, but the males are normally brown/white/black or black/white.
The lesser wax moth is a small moth of the snout moth family (Pyralidae) that belongs to the subfamily Galleriinae. The species was first described by Johan Christian Fabricius in 1794. Adults are about 0.5 inches (13 mm) in length and have a distinct yellow head with a silver-grey or beige body. Lesser wax moths are common in most parts of the world, except in areas with cold climates. Their geographic spread was aided by humans who inadvertently introduced them to many regions worldwide.
The elephant beetle is a member of the family Scarabaeidae and the subfamily Dynastinae. They are Neotropical rhinoceros beetles.
Galleria mellonella, the greater wax moth or honeycomb moth, is a moth of the family Pyralidae. G. mellonella is found throughout the world. It is one of two species of wax moths, with the other being the lesser wax moth. G. mellonella eggs are laid in the spring, and they have four life stages. Males are able to generate ultrasonic sound pulses, which, along with pheromones, are used in mating. The larvae of G. mellonella are also often used as a model organism in research.
Coccinellidae is a widespread family of small beetles. They are commonly known as ladybugs in North America and ladybirds elsewhere in the English-speaking world; "lady" referring to mother Mary. Entomologists prefer the names ladybird beetles or lady beetles to avoid confusion with true bugs. The more than 6,000 described species have a global distribution and are found in a variety of habitats. They are oval beetles with a domed back and flat underside. They are sexually dimorphic; adult females are larger than males. Many of the species have conspicuous aposematic (warning) colours and patterns, such as red with black spots, that warn potential predators that they are distasteful.
Helicoverpa assulta, the oriental tobacco budworm, is a moth of the family Noctuidae. H. assulta adults are migratory and are found all over the Old World Tropics including Asia, Africa, and Australia.
Lebia grandis is a ground beetle in the family Carabidae found in North America. It is a specialist predator on the eggs and larvae of Colorado potato beetles, and its larvae are obligate parasitoids of Colorado potato beetle pupae.
Hylobius transversovittatus is a species of weevil in the family Curculionidae. It is native to the Old World where both adults and larvae feed on purple loosestrife. This plant is regarded as an invasive species in North America and the weevil has been introduced into both the United States and Canada in an effort to control the plant.
Alphitobius diaperinus is a species of beetle in the family Tenebrionidae, the darkling beetles. It is known commonly as the lesser mealworm and the litter beetle. It has a cosmopolitan distribution, occurring nearly worldwide. It is known widely as a pest insect of stored food grain products such as flour, and of poultry-rearing facilities and it is a vector of many kinds of animal pathogens. In larval form, it is an approved novel food in the European Union, and also used as feed.
Callosobruchus chinensis is a common species of beetle found in the bean weevil subfamily, and is known to be a pest to many stored legumes. Although it is commonly known as the adzuki bean weevil it is in fact not a true weevil, belonging instead to the leaf beetle family, Chrysomelidae. Other common names include the pulse beetle, Chinese bruchid and cowpea bruchid. This species has a very similar lifestyle and habitat to Callosobruchus maculatus and their identities are often mistaken for each other. This beetle is a common pest targeting many different species of stored legumes and it is distributed across the tropical and subtropical regions of the world. C. chinensis is one of the most damaging crop pests to the stored legume industry due to their generalized legume diets and wide distribution.
Macrotera portalis is a species of communal, ground nesting, partially bivoltine bees found in arid grasslands and desert regions of North America. An oligolectic bee, M. portalis gathers pollen only from plants in the genus Sphaeralcea and has patterns of seasonal emergence to survive the harsh conditions of the desert, with emergence delayed until monsoon rains arrive.
