Just found out I'm allergic to dust mites!  The main species are cosmopolitan pyroglphids but I call them House dust mites. 
The main species are identified as:  The dust mites are cosmopolitan pyroglyphids.

House dust mite
House dust mites (HDM, or simply dust mites) are a large number of mites found in association with dust in dwellings. The main species are identified as:  The dust mites are cosmopolitan pyroglyphids. House dust mites, due to their very small size and translucent bodies, are barely visible to the unaided eye. A typical house dust mite measures in length. For accurate identification, one needs at least 10× magnification. The body of the house dust mite has a striated cuticle. They feed on skin flakes from humans, and animals, and on some mold. "Dermatophagoides farinae" fungal food choices in 16 tested species commonly found in homes was observed "in vitro" to be "Alternaria alternata", "Cladosporium sphaerospermum", and "Wallemia sebi", and they disliked "Penicillium chrysogenum", "Aspergillus versicolor", and "Stachybotrys chartarum".
Dust
Dust are fine particles of matter. It generally consists of particles in the atmosphere that come from various sources such as soil, dust lifted by weather (an aeolian process), volcanic eruptions, and pollution. Dust in homes, offices, and other human environments contains small amounts of plant pollen, human and animal hairs, textile fibers, paper fibers, minerals from outdoor soil, human skin cells, burnt meteorite particles, and many other materials which may be found in the local environment. House dust mites are present indoors wherever humans live. Positive tests for dust mite allergies are extremely common among people with asthma.
Aspergillus penicillioides
Aspergillus penicillioides is a fungus of the genus "Aspergillus", and is among the most xerophilic fungi. "Aspergillus penicillioides" is typically found in indoor air, house dust, and on substrates with low water activity, such as dried food, foxy papers and binocular lenses. The distribution of the fungus is worldwide as it has been found in bed dusts from maritime temperate, Mediterranean, and tropical climates. The abundance of the fungus is influenced by outdoor climate, with highest numbers found in tropics and lowest numbers in Mediterranean climate. Cool temperature tends to decrease number of "A. penicillioides" in house dusts.
Mite
Mites are small arthropods belonging to the class Arachnida and the subclass Acari (also known as Acarina). The term "mite" refers to the members of several groups in Acari but it is not a clade, and excludes the ticks, order Ixodida. Mites and ticks are characterised by the body being divided into two regions, the cephalothorax or prosoma (there is no separate head), and an opisthosoma. The scientific discipline devoted to the study of ticks and mites is called acarology. Most mites are tiny, less than in length, and have a simple, unsegmented body plan. Their small size makes them easily overlooked; some species live in water, many live in soil as decomposers, others live on plants, sometimes creating galls, while others again are predators or parasites.
Scabies
Scabies, also known as the seven-year itch, is a contagious skin infestation by the mite "Sarcoptes scabiei". The most common symptoms are severe itchiness and a pimple-like rash. Occasionally, tiny burrows may be seen in the skin. In a first ever infection a person will usually develop symptoms in between two and six weeks. During a second infection symptoms may begin in as little as 24 hours. These symptoms can be present across most of the body or just certain areas such as the wrists, between fingers, or along the waistline. The head may be affected, but this is typically only in young children.
Peptidase 1 (mite)
Peptidase 1 (mite) (), also known as endopeptidase 1 (mite), is an enzyme found in various species of mites. This enzyme exhibits cysteine protease activity with broad endopeptidase specificity. The various forms of peptidase 1 pertaining to individual mite species comprise the group 1 mite allergens. Following the naming conventions of allergens, these peptidase 1 variants include Der p 1 of the European house dust mite "Dermatophagoides pteronyssinus"; Der f 1 of the American house dust mite "Dermatophagoides farinae"; Eur m 1 of the Mayne's house dust mite "Euroglyphus maynei"; and Pso o 1 of the sheep scab mite "Psoroptes ovis".
Dander
Dander is an informal term for a material shed from the body of various animals, including humans, which have fur, hair, or feathers. The term is similar to dandruff, when an excess of flakes becomes visible. Skin flakes that come off the main body of an animal are dander, while the flakes of skin called dandruff come from the scalp and are composed of epithelial skin cells. The surface layer of mammalian skin is called the stratum corneum, which is shed as part of normal skin replacement. Dander is microscopic, and can be transported through the air in house dust, where it forms the diet of the house dust mite.
