Horsehair worms, part of the taxonomic phylum Nematomorpha, are parasitic worms that resemble long thin strands of hair (hence their nickname).
The bug that looks like a strand of hair is scientifically called Nematomorpha. The bug that looks like a strand of hair is scientifically called Nematomorpha. The term refers to a phylum in the Nematoida clade and includes the worms people call horsehair worms, Gordian worms, or hairsnakes.
Phylum Nematomorpha
The free-living adults are several centimeters to 1 m long and about 3 mm wide. They often appear like thin sticks or thick hairs and nonliving until they start to move. Their typical life cycle includes adults that reproduce sexually and lay eggs.
Horsehair worms are harmless to vertebrates, because they can't parasitize people, livestock, pets, or birds. They also don't infect plants. If humans ingest the worms, they may encounter some mild discomfort of the intestinal tract, but infection never occurs.
The treatment of choice is diethylcarbamazine (DEC), which kills the microfilariae and adult worms. Albendazole is sometimes used in patients who are not cured with multiple DEC treatments. It is thought to kill adult worms.
Identification. Horsehair worms are slender (1/25 to 1/8 inch wide), very long (4 to 24 inches), and yellowish-tan to brownish-black in color. They often squirm and twist, knotting themselves into a loose, ball-like shape, resembling the so called "gordian knot," in freshwater pools.
Permethrin lotion 1% is approved by the FDA for the treatment of head lice. Permethrin is safe and effective when used as directed. Permethrin kills live lice but not unhatched eggs. Permethrin may continue to kill newly hatched lice for several days after treatment.
Identification and Ecology of Australian Freshwater Invertebrates. The order Gordioidea takes its name from the mythical Gordian Knot. This is seen when several adult individuals tangle together to form a knot. Ecology: Adult horsehair worms occur in flowing and shallow standing waters.
People with loiasis can have itching all over the body (even when they do not have Calabar swellings), hives, muscle pains, joint pains, and tiredness. Sometimes adult worms can be seen moving under the skin.
Horsehair worms develop as parasites in the bodies of grasshoppers, crickets, cockroaches, and some beetles. When mature, they leave the host to lay eggs. They are not parasites of humans, livestock, or pets and pose no public health threat.
Hookworms are white or reddish-brown, very thin — like a strand of hair — and short, sometimes less than an inch long. Although they may be present in your pet's stool, they can be difficult to see with the naked eye. Your vet can make a diagnosis by looking for hookworm eggs from a fecal sample from your dog.
Threadworms, also known as pinworms, are tiny parasitic worms that infect the large intestine of humans. Threadworms are a common type of worm infection in the UK, particularly in children under the age of 10. The worms are white and look like small pieces of thread.
Horsehair worms are white when they first emerge from the host's body but turn yellowish-tan to brownish-black after a short time. The worms often squirm and twist in the water, knotting themselves into a loose, ball-like shape, resembling the "Gordian Knot." Another name for the horsehair worm is the Gordian worm.
Adult roundworms live in the intestinal tracts of their hosts, consuming that host's food. The adult roundworm is round, white to light brown in color, and several inches long. These worms look a lot like spaghetti or angel hair pasta.
Some common bugs that can be mistaken for lice are ants, bedbugs, and fleas. A few things all these bugs have in common is they're small in size, can be dark colored, and can give you an itchy head. A few things that can be mistaken for lice nits are dandruff, hair product, or dirt.
What are those thread-like strands floating in the water? Commonly referred to as horsehair, or cabbage worms, the Gordian worm is often mistaken for a thread of horse hair. The term "horsehair worm" was coined because people once thought horse hairs would spontaneously come alive in their horse's water troughs.
The most common symptoms of scabies, itching and a skin rash, are caused by sensitization (a type of “allergic” reaction) to the proteins and feces of the parasite. Severe itching (pruritus), especially at night, is the earliest and most common symptom of scabies.
Common parasitic skin diseases include creeping eruption, lice, and scabies.
The parasitic larvae that hatch need to complete their development inside the body of a relatively large insect. The larvae are ingested by a cricket, cockroach, beetle, or other insect that can then find its way into your home.
Summary. Pinworm is the most common worm infection in Australia. The major symptom is an itchy bottom, particularly at night.
The most common millipedes are dark brown and reach 1 to 1 1/2 inches when fully grown. They are round and elongated, with many small legs. When dead or disturbed, they tend to curl into a tight coil. Millipedes do not bite or pose any danger to humans.
Demodex. Demodex folliculorum and Demodex brevis are two species of tiny parasitic mites that live in the hair follicles and sebaceous glands of human skin, respectively. Both species are found primarily on the eyelashes and eyebrows or near the nose.
Key takeaways: Formication is the sensation that bugs are crawling on or under your skin when they don't really exist. Causes include mental health conditions such as depression, medical conditions like Parkinson's disease, certain prescription medications, or drug use.
