They are small spiders with very long, thin legs. Eight pearly eyes in three
groups, three eyes group in each side and two in the middle.. The abdomen is
long and cylindrical. The female warps the eggs with a few stand of silk and
hold in her chelicerae.
It is believed that their venom is one of the most poisonous, but the fangs
of these spiders are too small to cut our skin. However, this is not true.
Details see below.
Their venom is harmless to humans.
Up to now we only found one species in this family.
- This page contains pictures and information about Daddy Long-leg Spiders
that we found in the Brisbane area, Queensland, Australia.
to leg 50-100mm
Spiders live inside houses and buildings. They make tangled webs in the wall
corner and ceiling. When they are disturbed, they will vibrate very quickly on their web until it can't be seen. Their
body is small and legs are extremely
long and thin. Their body is silver colour with brown patterns. They are easily
almost in every garage in Brisbane.
- Daddy Long-Legs are the natural enemies of Red Back
Spiders which are known to hunt and feed on the Red Back. Daddy Long-Legs
are quite harmless to human and they are essentially the best method to control
the Red Back Spiders.
- The first picture shows a Daddy Long-leg approaching an Red Back spider. This spider does not make egg-sac, instead females carry the egg mass with
them wherever they go.
- In the wild Daddy Long-legs live inside large tree holes near ground and
shelters under rocks. The Daddy Long-leg in the above picture is very large, up to 100mm leg to
leg. It was nesting alone inside a burned tree hole. The pictures show it just
capture a small lacewing.
Questions for Discussion
We read quite a number of spider books stated that Daddy Longlegs spiders'
venom is one of the most poisonous, but the fangs of these spiders are too small
to cut our skin, so they are not considered as dangerous spiders. However, we
also read some spiders books they said that Daddy Longlegs' venom are harmless
to humans. We are confused. We think the 'most poisonous' point is more
interesting and it seems better to believe they are toxic than non-toxic. So we
put the ''most poisonous' information in our web page....... until our visitor
Justin Cordill sent us the email.
Justin Cordill kindly sent us the email advised that the Daddy Longlegs
spiders' deadliest venom is simply untrue. And he suggested us to contact with Dr. Robert (Spider Bob) G. Breene
III for more detailed explanation. Following is the advise from Dr. Robert
"It started out with the myth of harvestmen, Opiliones, one family
called daddylonglegs allegedly having deadly venom, but they couldn't cut
through the skin. In fact, Opiliones as an order does not have venom.
"The next urban myth was in response to this. The cellar or
daddylonglegs spiders have deadly venom, but couldn't bite through the skin.
Again, totally false.
"There have never been reports of problems with pholcids. Recluse
spiders are much less equipped to bite through skin than pholcids are. Their
chelicerae are fused, leaving only two tiny fangs to do the work, but if you
kill one with the fangs in contact with the skin, I'm sure you've seen some of
the results. Due to the effective treatment, the only dangerous aspect of
recluse bites is if the MD does not know the treatment.
"There exists a huge amount of bad information out there on arachnids,
and you appeared to have picked up on a lot of it."
Here we would like to thank Dr. Robert G. Breene and Justin Cordill again for
