 Long-bodied cellar spider - Pholcus phalangioides

Long-bodied cellar spider - Pholcus phalangioides
Harvard, Worcester County, Massachusetts, USA
October 1, 2004

The long-bodied cellar spider could be called a granddaddy-long legs,but it is not the same thing as a harvestman.See this article.

Do cellar spiders kill other spiders?
I appreciate the inclusion of a location for this spider. I saw many of these on Cape Cod, and at first I was a little frightened of them, until I read more about them. Now I've moved to Arizona, and I'm seeing similar spiders around my house. The reason why I bring this up is that I've read that cellar spiders actually kill, or keep away, more dangerous spiders like black widows and brown recluses. Is this true? If so, that would be nice. Arizona does seem to have a lot more black widows and brown recluses than other states I've lived in.

they kill insects and other spiders. They are a good house spider to keep around.

Cellar Spider
Not an expert...but this sure looks like a cellar spider (Daddy-long-legs) to me.

Cellar spider
After looking up cellar spider, I think this is a Long-bodied cellar spider, Pholcus phalangioides.

Long-bodied cellar spider
Isn't a "Daddy Long leggs" also a "Harvestman"? I was of the impression that a "Cellar" spider was (or is) closer to a "Nursery" (web) spider then a Daddy Long legs...?
>> Clarification, please. Forgive me, but I'm rather new to this.
Many thanks...


Harvestmen are known as Daddy-long-legs only as a regional common name....not scientific common name. The group of spiders known scientifically as Daddy-long-legs are the cellar spiders. (at least that's how I've come to understand it.) I know it confuses me too. See this discussion here Also see this article or Snopes

Daddy-Long legs
The Daddy-Long Legs is NOT the same type of spider as the Cellar Spider.Daddy-Long Legs refers to two types of spiders:the harvestman (Which is not a spider,because it does not have venom or spin webs.This type is still an arachnid,though.),and the spider (Which is not a long-bodied cellar spider).
The long-bodied cellar spider has nothing in common with the nursery web spider(except that they both are arachnids).Nursery web spiders are poisonous and larger than the long-bodied cellar spider.
Some people believe that long-bodied cellar spiders are the most venomous spiders in the world,but their mouths are not large enough to bite with.However,there is no evidence to support this.This myth probably came from the fact that they do kill venomous spiders,such as the black widow and brown recluse.
Because of this,long-bodied cellar spiders are very useful to have around your house.They can help keep most pests away without causing any harm to people.

Cellar Spiders can be called Daddy-long-leg spiders
If you look at Levi's common name for the Family Pholcidae he calls them Daddy-long-legs Spiders. Then he specifically says... "not to be confused with Phalangidae".

Also none of the nursery web spiders in the US or Canada have a bite that would be of medical concern. The term poisonous is usually used for something a person eats... but I assume we're not worried about people eating the spiders.

I do agree with your point that cellar spiders/daddy-long-leg spiders (Pholcidae) are beneficial to have in the home.
