One single spider living in my timber insect hotel. Bright green and yellow. No foliage. No camouflage.  Never seen one like it before.  Hoping you can educate me?

Red Spotted Cetratus

Dear Colleen,
The longer length on the two front pair of legs is a good indication that this is probably a Green Huntsman Spider which is pictured on both the Australian Museum site and Oz Animals.  Your spider does look different though, so we are requesting some additional information.  What is a “timber insect hotel”? because it implies this Spider is being kept in captivity.  Huntsman Spiders do not build webs.  We would also like to know the approximate size of your spider.  Crab Spiders in the family Thomisidae also have two pairs of front legs that are longer, and they are generally smaller than Huntsman Spiders, so that is also a strong possibility.  Crab Spiders do not build webs, but there are no individuals pictured on the Brisbane Insect site that resemble your individual.  The abdomen on your individual is also shaped quite differently than that of most Crab Spiders.

Thank you for your response. I will give you more details later.
In the meantime, rest assured I keep NOTHING in captivity.
Insect hotels are difficult to explain, so if you Google “insect hotel” all will be revealed.
Thanks again. Such an interesting creature.
I’ll get back to you.
Colleen.

Update:  Red Spotted Cetratus
Thanks to a comment from Cesar Crash who runs the Brazilian site Insetologia, we have a link to the site Arachne.org and the Red Spotted Cetratus where it states:  “A green crab spider with orange to red spots found Australia wide in moist habitats. The spots cluster at the rear of the cigar shaped, wrinkled abdomen. The whole spider can be plain green or even brownish. The first two pairs of legs are much more robust and longer than the others. The cephalothorax is relatively wide and slighly domed with orange on the eye region. The eyes are circled with white. Well camouflaged on green leaves where it seeks prey by ambush.”   There are also nice images on BowerBird.

Greetings What’s That Bug!
Okay, I know this is an orbweaver spider. However, I’m not sure which one. Is it Eriophora ravilla? Is it Neoscona crucifera? Is it something completely different? Whatever it is, that bright red color sure stands out. This picture was taken at approximately 8:30 a.m. at Winding Waters Natural Area in West Palm Beach, Florida. Most of the web was down, whether that was from the dragonfly tearing it apart or the spider was doing some housekeeping. Thanks for shedding some light on this colorful spider.

Orbweaver eats Dragonfly

Dear Ann,
Your Food Chain image is stunning, but alas, we are not comfortable providing a definitive identification, but your individual does resemble several orange
Neoscona crucifera individuals pictured on BugGuide.

Thanks for trying to identify this spider. Sometimes I wish these guys came with name tags! J

Fungus Infested Cellar Spider

Dear Mary,
When it was alive, this Cellar Spider was not a threat to humans.  Like most Spiders, Cellar Spiders are venomous, but the bite is not considered a threat to humans.  This Cellar Spider is dead and being consumed by Fungus.  Cellar Spiders with Fungus Infestations are relatively common in our archives.

Thank you!
Quite an unusual image
When I put the photo in google images
Google identified it as some kind of light.
( does look like lightning)
Wondering if the mold that killed the spider is dangerous to humans..

Trapdoor Spider

Dear Mysticz,
This is a gorgeous Spider.  It has such a distinctive appearance, including the red tips on the legs.  We could not locate any exact matches on the internet, but we did find this image on FlickR of a Tube Trapdoor Spider from Singapore that looks somewhat similar.  We are quite confident your individual is a Trapdoor Spider, but we are not certain to which family it belongs.  The closest visual match we could locate is a posting to Encyclopedia of Life of
Idiops constructor, a member of the family Idiopidae, which Wikipedia calls the Armored Trapdoor Spiders.

Trapdoor Spider

Thanks for the effort Daniel.

Hi there! This guy was trying to rent a room from us (in South Caribbean of Costa Rica). We successfully removed him from our front door, but curious what kind he was?

Probably Nursery Web Spider

We believe this is a Nursery Web Spider in the family Pisauridae, possibly one of the Fishing Spiders, but its markings are unusual.

Dome Web Spider

Your colorful spider is a harmless Orbweaver, and we believe we have correctly identified it as a Dome Web Spider or Tent Spider, Cyrtophora moluccensis, thanks to images posted to Brisbane Insects where it states:  “Tent Spiders build tent-shaped webs between plants and bushes. Their tent shaped webs are easily recognized, up to 60cm in diameter” and “Unlike the other spider webs, the webs of  Tent Spiders and Russian Tent Spiders do not have sticky silk. The spiders rest upside down in the middle of the tent from day to night. Sometimes we can see a few of the Tent Spiders build their tent webs joined together and cover an area of a few meters.”  We also found images on Deviant Art and Bush Pea.
