Spider Photos - Trapdoor Spiders

The name Trapdoor spider covers several families and many different species. Trapdoor spiders include the Funnel-web, Mouse, Whistling, and Curtain-web spiders; they are distinguished by the stocky body, long leg-like palps, and two knee-like lobes to which the fangs join (chelicerae) in front. Most live in burrows with or without trapdoors in the ground, but some live in trees. Trapdoor spiders have powerful chelicerae and four pale patches (the book-lungs) under the abdomen. The correct identification of Trapdoor spiders is often quite complicated.  Trapdoor spiders can be distinguished from the more dangerous Funnel web spider by its brown or mottled markings. When in danger, a Trapdoor spider will freeze or flee whereas a Funnel web will rear back aggressively. Trapdoor spiders construct burrows lined by their silk and closed by a hinged door of silk, moss, and soil. There they lie in wait for passing prey, usually an insect; when the prey touches silken threads radiating out on the ground near the door, the spiders quickly open the door and seize it. Closely related to Tarantulas, Trapdoor Spiders make up the family Ctenizidae. They range in size from 1.5 cm - 3 cm in body length, are harmless to humans, and are found in many warm climates. They also use their burrows for protection and as nest sites, the female spinning her egg sac for about 300 eggs in the burrow.

VERY aggressive little beast, rather that run, prefered to stand and bare his rather large shiny black fangs (sadly failed to get a decent shot of those). In Adelaide, South Australia, June 2017. Never seen one like this before here (hope not to again). Was about the size of a decent Huntsman but quite a red hue.

Hello, I could sure use some help! I am constantly finding these spiders inside my house and on my porches. They are quite large, about the size of a quarter. I have found about 10-15 so far, never seen them before why all of the sudden are they coming in now?? It is mid March, i am east of Houston Texas and live on a swamp.. I absolutely hate spiders and am deathly afraid of them! I would love to know how to keep them AWAY! We have already sprayed our home inside and out with Demon. Any help is appreciated! Thanks!?

Hi Glen, I was looking through your site to see if I could ID these two large spiders that I found while pulling weeds in my yard. I live in North Texas. The red one jumped on my hand and ran up my arm. I flung it off and took a photo, then found the darker one. Neither were aggressive or shy. I figure they aren't harmful and left them alone. They were similar enough and in close proximity, that I suspect they could be male and female of the same species. Odd looking and probably the size of a 50 cent piece. Any idea what they are exactly? I have NEVER seen them in all the places I have been in Texas. Sincerely, Tammy

Hi Glen Happy New Year to you. I would be most grateful if you can identify this spider please. It was roaming in my back yard (rural setting in Victoria, Australia) I nearly stood on it!! I'm also curious to know why it would be out during the day? I watched it for ages through a telescope. It sat quietly with its legs tucked in around it, like it was trying to be as small as possible. Every now and then it's front legs and fangs would move which a guessed it was eating something like ants??? There were lots of ants around. After a while it decided to go for a wander and that's when the birds spotted it. One attacked it. Spider played dead. Then another attacked. Spider lost a leg and then the first bird took off with it. I presume it was dead. It was amazing. I didn't know birds could eat a venomous spider! Any info you can provide will be very much appreciated. Thank you. Kind regards Anne

Greetings, A week or so ago, well above the tidal zone, we found a large unknown spider sitting stationary. It was before 8AM, cold and breezy. As the spider was in danger of getting eaten by seagulls, or stepped on by beach-goers, we scooped it up, took it higher into the dunes, released it at the edge of some vegetation. Checking NWF Field Guide to Insects and Spiders of North America, I could not find a match. Can you take a look at the attached and advise what specie this spider might be? The spider looked like a small tarantula, it was that large. Thank you, Cait, San Jose

Ugly red/brown one: We were Camping in Mt. Hood Forest sitting around a small fire and more than a dozen of these big fellows would come crawling out of the dark to the flames. What are they? The size reference is a little hard, the grass and twigs around it are pretty small but the spiders were bigger than quarters, definitely.

Hi, I've been searching the net for info on a couple of spiders and was hoping you could give me a more accurate identification: This one I found on the wall of my house on the Yorke Peninsula, South Australia, I thought it might be called an Adelaide Trapdoor or Adelaide Funnelweb? Its very orange in colour and I've only seen 2 or 3 in my life

I am hoping you can help me identify these different spiders. I came across the lighter brown spider running around my parents farmhouse in Sacramento. The other spider I am guessing is a Male California Trapdoor Spider? I found it hanging on our screen door in San Diego after our first heavy November rainfall...possibly looking for a mate? I heard these are rare creatures now, my grandma used to catch them as a young girl in Glendale 1930's . I've never encounter spiders this large until I saw your website, super informative and great pictures!! Megan

More Info from Mia:
14 April, 2009: We have successfully identified our spider (Named Trapper) Your right she wasnt a wolf spider but a varation of Trapdoor spider closely related to a Tarantula. Ive been trying to figure out some more info in regards to her such as possible hybernation or dormancy and an approximate lifespan. A lil info I thought I would pass on to you. Calisoga longitarsus "Trapper is no wolf spider though. Those eyes are all wrong. This is definitely one of the mygalomorphs. Where do you live? I'm guessing California or out west for sure. Appears very much to be a female Calisoga longitarsus from the Nemesiidae family (Tube-trapdoor spiders). Sometimes referred to as false tarantulas due to the resemblance of their relatives. She's not dangerous, I can assure you of that. Her bite will be painful most likely (in the event of a bite), but should be no worse than that of a bee sting and symptoms should subside within 24 hours. That being said, I'm not sure how well this spider will enjoy being handled so I advise caution. People tend to label any large hairy spider as wolf spiders when the don't know any better. Wolf spiders are actually pretty easy to identify once you know what to look for as they have a rather distinct eye pattern. Spider families are differentiated mostly by eye patterns. A good resource for this can be found here: http://bugguide.net/node/view/84423" I have a few more pictures if you would like as well here is the link for the page she is currently housed upon on your site http://spiderzrule.com/trapdoor1.htm Many regards and thanks so much once more Mia
Reply: This could be a trapdoor spider but it is rather light in colour. It doesn't have the correct eye pattern for a wolf spider- glen
22 November, 2008:
I live in Northern California in the Tahoe area. My neighbour just across the driveway found this in her front yard. I've caught what I think it be a female and she is thriving. However, Im perplexed. Just what is she? I at first thought a Trap-Door Spider. She does burrow but has no trap door. Instead its lined in a fine layer of webbing inside and out. So I am thinking maybe a Burrowing Wolf spider. Could you please shed some light? Also how venomous would she be? Ive not handled her and I really don't intend to. But we have grown to love her and its really for curiosty sake. Thanks a ton for your help and wonderful site. Keep it up.

Glen, I stumbled upon your web site and came to the conclusion that you are the "Spider Man"! I thought you might be able to help me identify this spider. This is the second one I have found in my house. The first one we found running across the floor this past Saturday was twice the size of this one but looked just like it. Thank you in advance for your time. Sincerely, Tonya

Glen, found this guy crawling on my buddy at work last week (Southern Idaho). We both thought it is a Hobo. Over the next few days, we saw 5 or 6 more just like it. They are rather large at about 1 1/2 inches long. Please let me know what it is. Thanks, Ken
