Daddy Longlegs: Spiders & Other Critters
Daddy longlegs is a term used to refer to three dissimilar types of critters, and only one of them is a spider. A common belief is that daddy longlegs spiders are the most venomous spiders in the world. However, that is an urban myth.
Harvestmen & crane flies
The term "daddy longlegs" nigh properly refers to an arachnid in the order Opiliones, which are too called harvestmen, according to the department of entomology, soils, and plant science at Clemson University. This outdoor arachnid typically lives under logs or rocks. Unlike spiders, information technology has simply i pill-like trunk segment. It also has only two eyes, does non spin webs, and is not venomous. Wisconsin Natural Resources mag wrote that, similar the spider, it has 8 very long legs that can be xxx times as long every bit its body.
In the Southern United States as well equally some parts of Canada and the United Kingdom, the crane fly is besides sometimes chosen a daddy longlegs, co-ordinate to The Burke Museum of Natural History and Culture. This distinctive bug, with six long legs and two large wings, is not a spider, nor an arachnid, but is an insect.
Cellar spiders
Another creature often called daddy longlegs is a spider in the family Pholcidae. The common name for these creatures used to be cellar spiders, but arachnologists have started to call them "daddy longlegs spiders" considering of the common confusion, reported the section of entomology at the University of California, Riverside.
These daddy longlegs have two body segments — a cephalothorax and an unsegmented abdomen. Jo-Anne Nina Sewlal, an arachnologist at the University of the West Indies in Trinidad, described the belly every bit "very prominent" and "either circular or oval shaped." Like other spiders, these daddy longlegs accept viii eyes, which Sewlal said are "arranged into a central pair and two clusters of three on either side of this pair."
Daddy longlegs spiders range in colour from cream to brown or grayness, and according to SF Bay Wild fauna, some species have brown stripes on the ventral side of their torso. The daddy longlegs' feature long, skinny legs are several times the length of its pocket-size body. Daddy longlegs spiders can range from 2 to 10 mm long, but their legs tin can grow up to fifty mm co-ordinate to the entomology department at Pennsylvania State University. The female is slightly bigger than the male.
According to Sewlal, daddy longlegs' long legs allow them to put less of their leg in contact with their spider web silk, making it less likely for them to get defenseless in their own web. She said this is the case for most web-weaving spiders, which have longer, slenderer legs than wandering, or ambushing spiders.
Daddy longlegs spider habits
Daddy longlegs spiders alive on every continent except Antarctica. They prefer clammy climates but tin nevertheless thrive in deserts. According to the section of entomology at the University of Kentucky, they are especially successful in urban areas where they spin thin, tangled webs in ceiling corners, under piece of furniture, in garages, barns, attics, and basements, and other places where they're unlikely to be disturbed. Daddy longlegs may be useful spiders because they tin assistance go on the population of other insects and spiders down, according to the Queensland Museum.
The daddy longlegs spider's spider web does not have adhesive properties for catching casualty. Co-ordinate to BioKIDS, insects and other spiders get trapped in the confusing, irregular web structure. Then, the daddy longlegs covers the prey with silk and administers its fatal bite.
Sewlal described 2 fascinating defense mechanisms of daddy longlegs spiders. She said that some neotropical species appoint in an action chosen "whirling." She described information technology as when "the spider holds onto the underside of its spider web and swings its body in horizontal circles until it looks like a mistiness to the human eye. This is a defence force mechanism and serves to make the spider appear bigger than information technology really is. This is especially useful since they have visual predators such as birds, lizards and even other spiders similar some species of jumping spiders.
"Another behavior that has a like purpose is called 'bobbing,'" said Sewlal. Again, the spider holds onto the underside of its spider web, and there it "repeatedly bends and straightens its legs like it is doing squats."
Mating
Daddy longlegs spiders can mate throughout the year. According to the Natural History Museum of Los Angeles County, like near spiders, the male squirts sperm onto the spider web and then sucks it up into his pedipalps, a pair of sensory appendages near the mouth. It and so inserts the pedipalps into the female's epigynum (external genital opening), and she carries the sperm around with her until she lays her eggs.
According to Clemson University, daddy longlegs spiders carry their egg sacs in their jaws at all times — with the exception of eating — until the eggs hatch. So, the newly hatched babies crawl onto the female parent's body for a brief stretch of time. It takes about a twelvemonth for the baby spiders to develop from egg to adult. Male daddy longlegs typically alive for about one yr and die afterward mating. Females tin live for 3 years.
Venom myth busted
According to urban fable, daddy longlegs are the most venomous spiders in the world, simply their fangs are too weak to penetrate man peel. All the same, this myth was busted on the Discovery Aqueduct show "Mythbusters." A daddy longlegs spider was coaxed into biting the arm of the show's co-host, Adam Savage. He reported nothing more than a very balmy burning sensation from the spider'due south venom that lasted only a few seconds.
According to the Australian Museum, the myth may have come up nearly because the daddy longlegs spider can kill the dangerous Australian redback spider, only that is washed through its ingenious web-catching technique, not its venom.
Taxonomy/classification
Daddy longlegs spiders (Cellar spiders)
Co-ordinate to the Integrated Taxonomic Data System (ITIS), there are more than eighty genera of daddy longlegs spiders and most 1,000 species. The taxonomy of cellar spiders is:
- Kingdom: Animalia
- Subkingdom: Bilateria
- Infrakingdom: Protostomia
- Superphylum: Ecdysozoa
- Phylum: Arthropoda
- Subphylum: Chelicerata
- Grade: Arachnida
- Order: Araneae
- Family: Pholcidae
Harvestmen
The taxonomy of harvestmen, co-ordinate to ITIS, is:
- Kingdom: Animalia
- Subkingdom: Bilateria
- Infrakingdom: Protostomia
- Superphylum: Ecdysozoa
- Phylum: Arthropoda
- Subphylum: Chelicerata
- Class: Arachnida
- Gild: Opiliones
In that location are well-nigh 6,500 species of harvestmen.
Crane flies
- Kingdom: Animalia
- Subkingdom: Bilateria
- Infrakingdom: Protostomia
- Superphylum: Ecdysozoa

At that place are 3 subfamilies, more than 500 genera and more than fifteen,000 species of crane fly.
