Even I , a humble daddy long legs, cannot help but be bored by Robin Micheal.
Oh by the way, we hate the term 'crane fly" it is our equivalent of "nigger". |
|
|
| I've always called the long-legged harmless spider a daddy long legs, not the crane fly. |

Pholcidae
From Wikipedia, the free encyclopedia Jump to: navigation, search Daddy long-legs spider Pholcus phalangioides Scientific classification Kingdom: Animalia Phylum: Arthropoda Class: Arachnida Order: Araneae Suborder: Araneomorphae Superfamily: Pholcoidea Family: Pholcidae C. L. Koch, 1851 Genera Holocnemus Modisimus Pholcus Physocyclus Psilochorus Smeringopus Spermophora many others Diversity 80 genera, c. 1000 species The Pholcidae are a spider family in the suborder Araneomorphae. Some species, especially Pholcus phalangioides, are commonly called granddaddy long-legs spider, daddy long-legs spider, daddy long-legger, cellar spider, vibrating spider, or house spider. Confusion often arises because the name "daddy long-legs" is also applied to two distantly related arthropod groups: the harvestmen (which are arachnids but not spiders), and crane flies (which are insects). Contents [hide] * 1 Appearance * 2 Habitat * 3 Behavior o 3.1 Trapping o 3.2 Threat Response o 3.3 Diet o 3.4 Gait * 4 Systematics * 5 Misconceptions * 6 References * 7 External links [edit] Appearance Pholcids are fragile spiders, the body being 2–10 mm in length with legs which may be up to 50 mm long. Pholcus and Smeringopus have cylindrical abdomens and the eyes are arranged in two lateral groups of three and two smaller median contiguous eyes. Eight and six eyes both occur in this family. Spermophora has a small globose abdomen and its eyes are arranged in two groups of three and no median eyes. Pholcids are gray to brown with banding or chevron markings. The shape of the Pholcus and Smeringopus's body resembles that of a peanut shell. [edit] Habitat Pholcids are web-weaving spiders and are distributed worldwide. They hang inverted in messy, irregular, tangled webs. These webs are constructed in dark and damp recesses, in caves, under rocks and loose bark, abandoned mammal burrows in undisturbed areas in buildings and cellars, hence the common name "cellar spiders". However, Pholcids are also quite commonly found in warm, dry places, such as household windows. [edit] Behavior [edit] Trapping The web has no adhesive properties but the irregular structure traps insects, making escape difficult. The spider quickly envelops its prey with silk and then inflicts the fatal bite. The prey may be eaten immediately or stored for later. [edit] Threat Response When the spider is threatened by a touch to the web or when too large a prey becomes entangled, the spider vibrates rapidly in a gyrating motion in its web and becomes blurred, almost invisible. For this reason pholcids have sometimes been called "vibrating spiders", although they are not the only species to exhibit this behaviour. Doing so might make it difficult for a predator to see exactly where the spider is, or may increase the chances of capturing insects that have just brushed their web and are still hovering nearby [1]. If the spider continues to feel harassed it will retreat into a corner or drop from its web, and leave the harasser alone. [edit] Diet Certain species of these seemingly benign spiders invade webs of other spiders and eat the host, the eggs or the prey. In some cases the spider vibrates the web of other spiders, mimicking the struggle of trapped prey to lure the host of the web closer. Pholcids are natural predators of the Tegenaria species, and are known to attack and eat redback spiders and huntsman spiders [2][3]. It is this competition that helps keep Tegenaria populations in check, which may be advantageous to humans who live in regions with dense hobo spider populations.[citation needed] Close-up of a Cellar spider's head, showing two groups of three closely clustered eyes [edit] Gait Pholcus phalangioides often uses an alternating tetrapod gait (first right leg, then second left leg, then third right leg, etc.), which is commonly found in many spider species. However, frequent variations from this pattern have been documented during observations of the spiders’ movements. When not in their webs, pholcids walk with an unsteady, bobbing action.[citation needed] [edit] Systematics For a complete list of the genera and species in this family, see List of Pholcidae species.

Indeed, pholcid spiders do have a short fang structure (called uncate). However, brown recluse spiders also have uncate fang structure, but are able to deliver medically significant bites. Either pholcid venom is not toxic to humans or there is a musculature difference between the two arachnids, with recluses, being hunting spiders, possessing stronger muscles for fang penetration. [5] In 2004, the Discovery Channel show MythBusters set out to test the daddy long-legs myth (Season 1, Episode 13 "Buried in Concrete"). After measuring the spider's fangs at approximately 0.25 mm (average human skin thickness varies from about 0.5mm to 4mm), the show's host was apparently bitten, although the bite produced little more than a mild short-lived burning sensation. This appears to confirm the suspicion that pholcids can penetrate human skin, but that their venom is practically harmless to humans. Additionally, recent research by Alan Van Dyke has shown that pholcid venom is actually relatively weak in its effects on insects as well.[6]. According to the University of California at Riverside, the daddy long-legs spider has never harmed a human and there is no evidence that they are venomous to humans.[7] [edit] References 1. ^ Bruce Marlin (2006-04-25).

Adults are very slender, long-legged flies that may vary in length from 2–60 mm (tropical species may exceed 100 mm). In the United Kingdom, South Africa, Australia, New Zealand and Ireland they are commonly referred to as daddy long-legs, but this name can also refer to two unrelated arthropods: members of the arachnid order Opiliones (especially in the United States and Canada) and the cellar spider Pholcidae (especially in Australia). Numerous other common names have been applied to the crane fly, many of them more or less regional, including mosquito hawk, mosquito eater (or skeeter eater), gallinipper,[1] gollywhopper,[1] and jimmy spinner.[citation needed] At least 14,000 species of crane flies have been described, most of them (75%) by the specialist Charles Paul Alexander. This makes the Tipulidae the largest family of Diptera.

Notice the mouth parts, the compound eyes and the antennae In appearance crane flies seem long and gangly, with very long legs, and a long slender abdomen. The wings are often held out when at rest, making the large halteres easily visible. Unlike most flies, crane flies are weak and poor fliers with a tendency to "wobble" in unpredictable patterns during flight, and they can be caught without much effort. Also, it is very easy to accidentally break off their delicate legs when catching them, even without direct contact. Crane flies vary in size, with temperate species ranging from 2 mm up to 60 mm, while tropical species have been recorded at over 100 mm. The Giant Crane Fly (Holorusia rubiginosa) of the western United States can reach 38 mm (1.5 inches). Some Tipula species are 64 mm (2.5 inches). Many smaller species (known as bobbing gnats) are mosquito-sized, but they can be distinguished from mosquitoes by the V-shaped suture on the thorax, non-piercing mouthparts, and a lack of scales on the wing veins. Female abdomens contain eggs, and as a result appear swollen in comparison to those of males. The female abdomen also ends in a pointed ovipositor that may look somewhat like a stinger but is in fact completely harmless. Adult mouthparts may occur on the end of the crane fly's long face, which is sometimes called a snout or a short rostrum. Larvae have a distinct head capsule, and their abdominal segments often have long fleshy projections surrounding the posterior spiracles (almost like tentacles). [edit] Ecology Despite their common names, crane flies do not prey on mosquitoes as adults, nor do they bite humans. [2] Adult crane flies feed on nectar or they do not feed at all; once they become adults, most crane fly species live only to mate and die. Their larvae, called "leatherjackets", "leatherbacks", "leatherback bugs" or "leatherjacket slugs", because of the way they move, consume roots (such as those of turf grass) and other vegetation, in some cases causing damage to plants. The crane fly is occasionally considered a mild turf pest in some areas. In 1935, Lord's Cricket Ground in London was among the venues affected by leatherjackets: several thousand were collected by ground staff and burned, because they caused bald patches on the wicket and the pitch took unaccustomed spin for much of the season.[3] Little is known of the juvenile biology of many crane fly species. The larvae of less than 2% of the species have been described. Of those that have been described, many prefer moist environments, and some leatherjackets are aquatic. The long legs are an adaptation that may allow the fly to alight in grassy places.[citation needed] Crane flies are a food source for many birds. They are also susceptible to fungal infections and are a food source for many other insects.[citation needed] [edit] Misconceptions Main article: Pholcidae #Misconceptions An urban legend states that the daddy long-legs spider has the most potent venom of any spider; this same legend is attributed to crane flies where they commonly go by the name "daddy long-legs" (principally in the United Kingdom). In fact, the crane fly is innocuous, while the spider's venom is harmless to humans because of the small dosage. The commonly confused harvestman, also known as daddy long-legs but which isn't a spider, is also not venomous.

I wondered about this, I never knew they were called crane flies! There seems to be some confusion.
1. I think this is a spider, and I'm sure everybody agrees here. http://www.primrose-london.co.uk/images/house%20spider1.jpg 2. I think this is a daddy-long-legs, although they normally have more legs, don't they? http://static.guim.co.uk/sys-images/Guardian/About/General/2009/6/7/1244400338947/Daddy-Long-Legs-Crane-Fly-001.jpg 3. I can't find a picture of a harvestman - but I think they look like spiders, but they're a lot thinner and a bit less scary. I think they eat spiders... I'm not sure though. Most of my family, including me, is terrified of spiders. I remember the first time my sister saw a daddy-long-legs, she said 'What?! I thought spiders were bad enough. NOW THEY'VE GOT WINGS!' |

Caspian - No 1 looks to me very much like the crane fly - daddy-long-legs.....I found them to be much more common in London and Southern England generally than they are up here in Scotland...our insect speciality here is the midge....Scotland is well known for this wee pest - totally harmless even tough they do bite for your blood and are singly very tiny but in swarms they are intensely irritating, especially on still, warm, humid summer evenings.
No 2 - it looks ugly and threatening even though it isn't dangerous at all...none of our spiders are - but I haven't a clue what kind it is....check it out on this Wild About Britain site: http://www.wildaboutbritain.co.uk/pictures/showgallery.php/cat/30 |
