Daddy longlegs, also known as harvestmen, are fascinating creatures often mistaken for spiders. However, they belong to a separate order of arachnids called Opiliones. These critters can be easily distinguished by their oval bodies, where the head and abdomen segments appear fused, and their extraordinarily long, wiggly legs.
Not only do they lack silk glands, but daddy longlegs are also not venomous. They have some unique features that set them apart from their spider cousins. For example, these creatures possess only two eyes and are known for their ability to detach a leg when threatened by predators, similar to how lizards can break off part of their tails.
Increasing your knowledge about daddy longlegs can help you appreciate their role in nature and dispel common misconceptions. Do not confuse them with cellar spiders, another type of arachnid known as “daddy longlegs.” Understanding the characteristics and habits of these arachnids can not only satisfy your curiosity but also contribute to better informed and responsible encounters with wildlife.
Daddy Longlegs Identification
Species Overview
Daddy longlegs, also known as harvestmen or cellar spiders, are arachnids, but not true spiders. They belong to the order Opiliones and can be found on every continent except Antarctica.
Distinguishing Features
Daddy longlegs are easily recognized by their:
- Long, slender legs
- Small, oval-shaped body
- Ability to lose a leg when attacked by a predator
Although they resemble spiders, daddy longlegs have some key differences:
Feature | Daddy Longlegs | Spiders |
---|---|---|
Body Segments | Single, oval | Two |
Eyes | One pair | Multiple pairs |
Venom Glands | Absent | Present |
Silk Production | Absent | Present |
Every Continent Except Antarctica
Daddy longlegs are remarkably adaptable arachnids and can be found on all continents except for Antarctica. They thrive in various habitats, including forests, grasslands, and even urban environments. This wide distribution demonstrates their adaptability and resilience in various conditions.
Daddy Longlegs Classification
Three Main Types
Daddy Longlegs are commonly mistaken as spiders but actually refer to a variety of arachnids and insects. Here are the three main types:
- Harvestmen
- Cellar Spiders
- Crane Flies
Harvestmen
Also known as Opilionids, these arachnids belong to the order Opiliones. Key characteristics include:
- Round or oval body
- Long, thin legs
- One pair of eyes
Although related, harvestmen differ from spiders as they have fused body sections and do not produce silk. They are harmless to humans, feeding primarily on decomposing vegetation and small insects.
Cellar Spiders
These creatures are also called daddy longlegs spiders, belonging to the family Pholcidae. Distinct features are:
- Small body with distinct head and abdomen
- Extremely long, thin legs
- Known for making messy webs
Contrary to popular myth, they are not venomous to humans and help control populations of other insects in homes.
Crane Flies
Although not actual spiders or arachnids, crane flies are sometimes confused with daddy longlegs, due to their long legs. Details about crane flies include:
- Insect belonging to the family Tipulidae
- Resemble oversized mosquitoes
- Harmless to people, no biting or stinging
Here’s a comparison table to better understand these three types:
Type | Arachnid/Insect | Venomous? | Can Produce Silk? |
---|---|---|---|
Harvestmen | Arachnid | No | No |
Cellar Spiders | Arachnid | No* | Yes |
Crane Flies | Insect | No | No |
*Note: Cellar spider venom is not harmful to humans.
In summary, each type of daddy longlegs has unique characteristics and plays a role in controlling pests in the ecosystem. By understanding their differences, we can better appreciate these fascinating creatures.
Daddy Longlegs Biology
Physical Characteristics
Daddy longlegs, also known as harvestmen, have an oval-shaped body with long legs. The body size ranges from about 1/16 to 1/2 inch long, and males typically have smaller bodies but longer legs than females (source). Some key features include:
- One pair of eyes
- Simple oval body
These creatures are often confused with cellar spiders, but there are some distinctions:
Misconceptions: | Daddy Longlegs (Harvestman) | Cellar Spider |
---|---|---|
Arachnid family | Opiliones | Araneae (Spiders) |
Venomous | No | Yes |
Produce silk for webs | No | Yes |
Venom and Fangs
Contrary to popular belief, daddy longlegs are not venomous, nor do they possess fangs. This misconception is often due to confusion with cellar spiders that do have venom (source).
Reproduction
The mating process in daddy longlegs can begin with an elaborate courtship dance performed by the male. The female then lays eggs, typically during the fall season, which hatch into youngsters after a period of time.
Daddy Longlegs Behavior
Prey and Feeding Habits
Daddy longlegs, also known as harvestmen, are omnivorous creatures that eat a variety of prey:
- Insects
- Spiders
- Snails
- Dead organisms
They often hunt in various habitats, such as gardens, grasslands, and under rocks. Interestingly, these arachnids use their long legs to sense vibrations from nearby prey.
Predators and Threats
The predators of daddy longlegs include:
- Birds
- Insects
- Rodents
To defend themselves, they can easily break off their legs, similar to the tail autotomy of lizards. Another interesting tactic is releasing an unpleasant odor to deter potential threats.
Mating and Courtship
Daddy longlegs exhibit a fascinating courtship process:
- Male initiates contact with female, using its legs to send signals
- Exchange of vibrations between the male and female
- Male deposits a spermatophore, which the female retrieves to complete fertilization
Daddy Longlegs | Spiders |
---|---|
Fused body | Separate cephalothorax and abdomen |
No silk glands | Can spin silk webs |
No venom glands | Possess venom glands |
In conclusion, daddy longlegs are fascinating arachnids with unique behaviors, from their feeding habits to their defense strategies and their way of mating. These creatures are an integral part of various ecosystems and are often overlooked or misunderstood by people.
Daddy Longlegs and Human Interaction
Do They Bite?
Daddy longlegs, also known as harvestmen, are often misunderstood arachnids. Despite popular belief, they are not venomous and do not bite humans as a form of attack or defense. In fact, they lack venom glands altogether, eliminating the possibility of a harmful bite to humans or other creatures^[1^].
Infestations and Pest Control
Daddy longlegs may be found in damp, dark areas such as basements or crawlspaces^[2^]. Though their presence can be uncomfortable for some, they aren’t considered dangerous pests. However, if you wish to remove them, using a broom or vacuum can quickly and harmlessly remove individual daddy longlegs. In more serious cases, contacting a pest control professional can help address infestation problems.
Coexisting with Daddy Longlegs
Rather than viewing daddy longlegs as nuisances, consider their benefits. They primarily feed on dead organic matter and small insects, resulting in a cleaner home environment. Coexisting can be simple as they pose no threat to humans and even play a crucial role in controlling other insects.
Pros and Cons of Daddy Longlegs in Your Home
Pros:
- Non-venomous and harmless to humans^[1^]
- Feeds on dead organic matter and small insects, aiding in pest control
Cons:
- May cause discomfort due to misconceptions about their nature
- Can be seen as unpleasant in a living space, especially in large numbers

Way nicer than the dull brown ones in Ontario Canada
Hi, I am doing a science project on Charles Darwin(‘s) voyage to the Chilean island of Valdivia and I have to pick a creature that is on the island that I was given. The Insect I chose is the Harvestman (also known as the Chilean spider) here is a picture http://www.whatsthatbug.com/images/opiliones_chile_gerhard.jpg
We are happy to learn that this image from our archives is helpful for your science project.
Hi,its Wyatt again,my science teacher wants us to give a detailed description of the creature,its diet,its habitat,behavior,and some interesting facts. Do you think you could help?
Wyatt,
We will not do your homework. You can look at our postings and follow any links we have already provided on our website because we have already done considerable research with posted identification requests. You can begin by looking at all postings in our Opiliones (that is the order to which they belong) and Harvestmen category to learn some general information about Harvestmen.
Dear Petie – after finding my insect I came straight to the net to try and identify her and your drawing was the closest i came to finding her! body was was small and round like a smartie and those legs just went on forever!
thank you for helping me to identify this gorgeous creature

Thanks for the link.
Hi,
I have also seen this spider and learned that this one is the man. The woman ist more round and with green stripes at its back. I also could provide a photo of the pair.
We would love an image. You may submit it using the Ask What’s That Bug? link on our site.
Hi,

Now this one I can answer a bit more confidently. This is not a harvestman, but a predatory mite of the genus Eatoniana (family Erythraeidae). This page has some photos of a similar species from Turkey.
Thanks for discovering this link for us. We will change the posting accordingly and search iSpot for matches in South Africa.
Thank you very much guys!
This one is a Sadocus funestis. I found some of them on Oncol national Park also near Valdivia city.
Thanks for your assistance.
This one is a male Sadocus polyacanthus.
Thanks for your assistance.
This is a spider, not a harvestman. I don’t know what kind it is but I think it may be some kind of orb-weaver. I did find another photo of the same species or something similar at http://www.richard-seaman.com/Travel/Philippines/Wildlife/index.html but without any ID.
Thanks for providing this link to a similar looking individual. We will change the subject line of the posting.
I believe this is a Tree Stump Spider (Araneidae: Poltys illepidus), found throughout Southeast Asia and Australia.
