Gasterophilus haemorrhoidalis (also called nose botfly or lip botfly) is a species of the genus Gasterophilus that lays eggs on the lips and around the mouth of horses, mules and donkeys. Their hatching is simulated by moisture from licking or feeding of hosts.
First instar development: Penetrate epidermis of the lips of hosts and migrate into mouth.
Second instar: move to stomach and duodenum(first section of small intestine)
Third instar: larvae become detached after some time and then pass to the rectum and re-attach themselves.
Appearance: Postsutural scutum with ground color uniformly brown or black legs yellowish brown, with femora distinctly darkened; abdomen ground color dark brown or black, with reddish-yellow or orangish setae posteriorly male with surstylus abruptly tapered distally, surstylar setae short, reaching at most halfway to the sagittal plane
Egg Description: Pedicel long and slender, with width/length ratio around 1/6 in lateral view, accounting for 2/5 of the total egg length.
In Equidae, third-stage larvae attach to the stomach, but also to the rectum, sometimes in great numbers. [1] Heavy infestation can cause anal prolapse in foals and mules.
They do not parasitise humans.
The luna moth, also called the American moon moth, is a Nearctic moth in the family Saturniidae, subfamily Saturniinae, a group commonly named the giant silk moths.
Botflies, also known as warble flies, heel flies, and gadflies, are a family of flies known as the Oestridae. Their larvae are internal parasites of mammals, some species growing in the host's flesh and others within the gut. Dermatobia hominis is the only species of botfly known to parasitize humans routinely, though other species of flies cause myiasis in humans.
Gasterophilus, commonly known as botfly, is a genus of parasitic fly from the family Oestridae that affects different types of animals, especially horses, but it can also act on cows, sheep, and goats. A case has also been recorded in a human baby.
Myiasis, also known as flystrike or fly strike, is the parasitic infestation of the body of a live animal by fly larvae (maggots) that grow inside the host while feeding on its tissue. Although flies are most commonly attracted to open wounds and urine- or feces-soaked fur, some species can create an infestation even on unbroken skin and have been known to use moist soil and non-myiatic flies as vector agents for their parasitic larvae.
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.
Gyrostigma rhinocerontis is the largest fly species known in Africa. It is a parasite of the black rhinoceros and the white rhinoceros.
Chrysomya is an Old World blow fly genus of the family Calliphoridae. The genus Chrysomya contains a number of species including Chrysomya rufifacies and Chrysomya megacephala. The term “Old World blow fly” is a derivative of both the associated family, Calliphoridae, and the belief that the genus Chrysomya originated in Asia and migrated to North America only relatively recently. Chrysomya’s primary importance to the field of medico-criminal forensic entomology is due to the genus’ reliable life cycle, allowing investigators to accurately develop a postmortem interval. Chrysomya adults are typically metallic colored with thick setae on the meron and plumose arista. The name comes from the word chrysos, meaning “golden” in reference to the metallic sheen of the genus’ species, and -mya, a derivation from the word myia, meaning “fly”.
Loxura atymnus, the yamfly, is a species of lycaenid or blue butterfly found in Asia.
Lucilia illustris is a member of the fly family Calliphoridae, commonly known as a blow fly. Along with several other species, L. illustris is commonly referred to as a green bottle fly. Lucilia illustris is typically 6–9 mm in length and has a metallic blue-green thorax. The larvae develop in three instars, each with unique developmental properties. The adult fly typically will feed on flowers, but the females need some sort of carrion protein in order to breed and lay eggs.
Calliphora loewi is part of the family Calliphoridae, bottle flies and blowflies, and in the genus Calliphora, blue bottle flies. The genus can be deceiving since C. loewi is not blue. Though this species is rare, it can play an important part in forensic entomology, spreading disease, and decomposing carrion. The life cycle of C. loewi is similar to the life cycle of the genus Calliphora. Since this species is rare there has not been very much research done with this species.
Cephenemyia ulrichii or the moose botfly, also called the elk botfly, moose nose botfly or moose throat botfly, is a large botfly that resembles a bumblebee. In the wild, they attack chiefly the nostrils and pharyngeal cavity of moose, but have been found in other deer species. There have also been several cases of C. ulrichii squirting their larvae into the eyes of human beings, a somewhat painful event that requires medical attention to forestall any possibility of serious damage.
Andesobia jelskii is a species of moth of the subfamily Arctiinae first described by Charles Oberthür in 1881. It is found in the Department of Junín in Peru.
Neodiprion abietis, commonly known as the balsam fir sawfly, is a species of insect in the family Diprionidae. It is found in North America from Canada to northern Mexico and is phytophagous, feeding on the needles of coniferous trees.
Dermestes ater is a species of beetle in the family Dermestidae, the skin beetles. It is known commonly as the black larder beetle or incinerator beetle. It is native to North America, but today it is found nearly worldwide. Like several other dermestid beetles, this species is a common pest of stored products.
Gasterophilus pecorum is a species of botfly within the genus Gasterophilus that is an obligate parasite of horses and other equids.
Eurybia elvina, commonly known as the blind eurybia, is a Neotropical metalmark butterfly. Like many other riodinids, the caterpillars are myrmecophilous and have tentacle nectary organs that exude a fluid similar to that produced by the host plant Calathea ovandensis. This mutualistic relationship allows ants to harvest the exudate, and in return provide protection in the form of soil shelters for larvae. The larvae communicate with the ants by vibrations produced by the movement of its head. The species was described and given its binomial name by the German lepidopterist Hans Stichel in 1910.
Heliothrips haemorrhoidalis is a species of thrips in the family Thripidae. It is most commonly known as the greenhouse thrips, the glasshouse thrip or black tea thrips. This species of thrips was first described in 1833 by Bouché in Berlin, Germany. H. haemorrhoidalis also has many synonyms depending on where they were described from such as: H. adonidum Haliday, H. semiaureus Girault, H. abdominalis Reuter, H. angustior Priesner, H. ceylonicus Schultz, Dinurothrips rufiventris Girault. In New Zealand, H. haemorrhoidalis is one of the four species belonging to the subfamily Panchaetothripinae.
Gasterophilus intestinalis, also known as horse bot fly, is a species of insect of the family Oestridae, and is found worldwide. The adults, which have a bumblebee-like appearance, are prominently active in the summer. G. intestinalis is primarily a parasite of horses, mules and donkeys.
Physocephala tibialis is a species of thick-headed fly found throughout the eastern United States, often near flowering plants. The adult fly is primarily black with a yellow face and thin white stripes on the abdomen. It is commonly found along the east coast of the United States and is often found near flowering plants.
Anastrepha fraterculus, known as the South American fruit fly, is a fruit fly species from the genus Anastrepha. A. fraterculus is a polyphagous, frugivorous fly that is a significant pest of commercial fruit production in South America.
