This medium sized light brown spider with dark stripes built his tunnel web in our aloe and cactus plants. Funnel web Spiders are known for their tunnel looking, funnel shaped webs.
These spiders are found all over the world. There are over 600 species of funnel-web spiders, belonging to the Agelenidae family.
We have several species of aloe desert plants on our property which the funnel web spiders seem to keep occupied. It is a fact that funnel-web spiders prefer moist environments.
Funnel web spiders are shy and come out at night. It was a cloudy day around the Tucson area and I was able to spot this arachnid repairing their web.
The broad funnel shaped web, looks like a tunnel ( see photo below ) and is made by the spider to connect to their burrow. When an insect enters the web the spider feels the vibrations and rushes out from the narrow end to bite its prey and inject it with venom.
The Arizona funnel-web spiders are NOT the same as the deadly Australian Funnel-web spiders, Atrax robustus, and are NOT dangerous to humans.
- The Australian Funnel-web spider is in the family Hexathelidae.
- The Arizona Funnel-web spider is in the family Agelenidae.
If you were bitten by SEVERAL funnel web spiders the venom could make you very ill and you should see a doctor.
Identifying a funnel-web spider: These spiders have distinctive grey and brown stripes and patterns. Funnel web spiders have long legs with little bristles and small eyes in 2 rows of four.
Funnel web spiders have been mistaken for Hobo and Wolf spiders. To identify a hobo spider it has a light stripe running down the middle of the sternum. When identifying a wolf spider remember wolf spiders DO NOT spin webs.
I am not crazy about spiders but they are very important to the ecosystem and health of our planet.
